Form 20-F for the period ended December 31, 2015

Results of Operations, page 63

 1. According to your disclosure on page 64, revenue in your consumer product segment decreased primarily
due to a disruption in the supply of barbecue charcoal and weak demand for bamboo vinegar. It appears there are known trends and
uncertainties that could materially impact your operations. As such, please expand your disclosures to highlight the underlying
factors that are impacting and might be expected to continue to impact your consumer products segment in fiscal year 2016. Your
disclosures should include sufficient detail for an investor to understand the underlying reasons behind the temporary disruption
and weak demand and whether those impacts are reasonably expected to continue in fiscal year 2016. See Item 303(a)(3) of Regulation
S-K. See also Section 501.02, 501.07 and 501.12 of the Financial Reporting Codification.

 2. Please expand your disclosures to quantify all the material factors that are disclosed as materially
impacting your results of operations. To the extent your disclosures include impacts due to volume of product provided, and/or
average price, please also ensure that those are sufficiently quantified for an investor to understand the impact of each. For
example:

 l Quantify the dollar amount of the decrease in sales of bamboo vinegar due to weak demand.

 l Quantify the dollar impact to sales from the changes in units and average selling prices of air purification products and deodorizer
products.

    1

 l Quantify the amount of the decreases in expenses for promotion, export and shipping and handling, which are described as the
key factors in the change in selling expenses.

These examples are not meant to be a comprehensive
list and are merely representative of issues noted throughout your discussion. Please refer to Item 303(a)(3) of Regulation S-K
and Section 501.12 of the Financial Reporting Codification for guidance.

Response:

We acknowledge
the Staff’s comments above and have revised our disclosure on pages 64-65 of Amendment No. 1 accordingly. For your reference,
it reads as follows:

In our
consumer product segment, the revenue decreased to approximately $43.2 million in 2015 from approximately $53.1million in 2014.
The decrease was primarily attributable to the decreased sales of barbecue charcoal designed for domestic market and lower sales
of deodorizer and bamboo vinegar in 2015. In particular, the revenue from barbecue charcoal for domestic market decreased by approximately
$4.9 million in 2015 compared to 2014. The decrease was primarily attributable to the temporary disruption in supply of barbecue
charcoal in the last two months of 2015. The environmental policies in certain localities has been tightened in Daxinganling Region.
Charcoal kilns are gradually shutting down by the government. From 2016, we are no longer able to purchase from our second largest
supplier Tahe Xinzhongda Carbon Co. The loss of one of the main suppliers could force us to look for alternative suppliers at higher
costs and thus increase our production costs in the coming years. In 2015, the overall household products sector experienced general
slowdown due to weak economy condition in China. Given the nature of our Charcoal Doctor line of products, people are increasingly
buying these household products online with unknown brands in order to save money. Therefore, orders from our major customers,
which are third party distributors and retail stores, have decreased considerably. We are expecting lower sale volumes from our
major customers in the coming years until the economic conditionsimprove. In particular, the revenue from bamboo vinegar products
decreased by approximately $2.8 million in 2015 compared to 2014.We sold approximately 0.6 million items of bamboo vinegar products
in 2015 compared to approximately 1.6 million items sold in 2014. The revenue from deodorizer products decreased by $1.5 million
in 2015 compared to 2014.We sold approximately 4.4 million pieces of air purification products and 7.7 million pieces of deodorizer
products in 2015 compared to approximately 4.9 million pieces and 7.9 million pieces sold in 2014. The average selling price of
air purification products increased by 11.9% while the average selling price of deodorizer decreased by 6.7% due to the change
in product mix.

Selling
expenses. Selling expenses decreased by approximately $222,000 to approximately $859,000 in 2015 compared to approximately $1.1
million in 2014. As a percentage of sales, our selling expenses decreased to 1.5% of revenues in 2015, as compared to 1.7% of revenues
in 2014. The decrease in selling expenses was primarily attributable to the decreased promotion expenses, decreased expenses related
to export and lower shipping and handling expenses in 2015. Due to the slowdown of our bamboo-based household products, the company
has removed our product billboards in several locations in Zhejiang Province. In addition, due to the decreasing sale and direct
export volume of our products, in 2015, promotion expenses, export expenses as well as shipping and handling expenses have decreased
by approximately 72%, 49%, and 33%, respectively, as compared to 2014.

 3. As of December 31, 2015, you have over eight months of sales in net accounts receivable. Please
expand your disclosure to provide an analysis of days sales outstanding for each balance sheet date presented. Address the payment
terms typically stipulated in your contracts and sales agreements and discuss the typical payment history. Discuss the underlying
reasons for significant instances of slow payment and receivables that remain outstanding for lengthy periods. Please provide us
with an aging of your accounts receivable as of December 31, 2015, detailing the total amounts outstanding at the balance sheet
date by categories of time, such as over 30 days, over 90 days, over six months, over one year, over two years, over three years,
etc. For each category, show the amount that has been subsequently collected.

Response:

We acknowledge
the Staff’s comment and the revised disclosure on page 74 of Amendment No.1 reads as follows:

Although we typically do not grant special payment terms to many of our customers, some of our customers, who are large retailors
and wholesale chains, tend to require longer payment terms that are over six months but unlikely to default. As of December 31,
2015, only approximately 2% of our outstanding receivable amounts were over one year. Our most recent review of collection information
indicated that $27.7 million has been collected by September 30, 2016, which represented 66% of the accounts receivable balance
as of December 31, 2015. The instances of slow payments and long-aging receivables may have negative impact on our short-term operating
cash flow but we have not experienced any significant defaults on those long-aging receivable. We periodically review our accounts
receivable and allowance level in order to ensure our methodology used to determine allowances is reasonable and accrued additional
allowances if necessary.

We acknowledge the Staff’s
comment and the revised disclosure on pages 75 of Amendment No.1 reads as follows:

We monitor our advances to suppliers
account and the allowance level periodically in order to ensure our methodology used to determine the related allowance is reasonable.

(or 84%) of the advance balances as of December 31, 2015 have been subsequently credited through the receipt of raw materials as

Response:

We acknowledge the Staff’s
comment and the revised disclosure for Item 15 on page 100 of Amendment No.1 reads in its entirety as follows:

 (a) Evaluation of Disclosure Controls and Procedures.

Under the supervision and with
the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness
of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e)
under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Disclosure controls and procedures are
controls and procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted
under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and
Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures
designed to ensure that information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated
to management, including our principal executive officer and our principal financial officer, as appropriate, to allow timely decisions
regarding required disclosure. Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer concluded
that our disclosure controls and procedures as of the end of the period covered by this report are effective.

 (b) Management’s annual report on internal control over financial reporting.

Our management is responsible
for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f)
under the Exchange Act. The Company’s internal control over financial reporting is a process that is designed to provide
reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external
purposes in accordance with accounting principles generally accepted in the United States and includes those policies and procedures
that:

 l Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect
the transactions and dispositions of the assets of the Company;

 l Provide reasonable assurance that transactions are recorded as necessary to permit preparation
of financial statements in accordance with accounting principles generally accepted in the United States and that receipts and
expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

 l Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition,
use or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations,
internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness
to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree
of compliance with the policies or procedures may deteriorate.

Under the supervision and with
the participation of our management, including our principal executive officer and principal financial officer, we conducted an
evaluation of the effectiveness of our internal control over financial reporting based on the framework established in the Internal
Control Integrated Framework issued by the committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) as
of December 31, 2015. Based on such evaluation, our management, including the CEO and CFO, has concluded that the Company’s
internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act of 1934) was effective
as of December 31, 2015.

 (c) Attestation report of the registered public accounting firm.

Not applicable.

 (d) Changes in internal control over financial reporting.
