(collectively, the “Reporting Persons”) as an amendment to that certain Schedule 13D filed by Dang Yu (George) Pan with the Securities and Exchange Commission (the "SEC") on November 13, 2007, as amended by Amendment No. 1 to Schedule 13D filed with the SEC on February 14, 2012, Amendment No. 2 to Schedule 13D filed with the SEC on February 14, 2018, Amendment No. 3 to Schedule 13D filed with the SEC on June 5, 2018, Amendment No. 4 to Schedule 13D filed with the SEC on March 15, 2019, Amendment No. 5 to Schedule 13D filed with the SEC on April 24, 2019, Amendment No. 6 to Schedule 13D filed with the SEC on July 2, 2019 and Amendment No. 7 to Schedule 13D filed with the SEC on September 12, 2019 (collectively, the "Schedule 13D"). Except as amended and supplemented herein, the information set forth in the Schedule 13D remains unchanged. Capitalized terms used herein without definition have meanings assigned thereto in the Schedule 13D.

Item 2.

Identity and Background.

Item 2 is supplemented by adding the following:

High Power Asset Management Inc. (“High Power Management”) is an exempted company incorporated with limited liability under the laws of the Cayman Islands. It is currently wholly owned by Mr. Dang Yu (George) Pan. Mr. Pan and Ms. Ping Chen are the directors of High Power Management. The principal business of High Power Management is investment management. The address of the principal office of High Power Management is at the Office of Sertus Incorporations (Cayman) Limited, Sertus Chambers, Governors Square, Suite # 5-204, 23 Lime Tree Bay Avenue, P.O. Box 2547, Grand Cayman, KY1-1104, Cayman Islands. Ms. Ping Chen is a Chinese citizen. Her business address is Building A1, 68 Xinxia Street, Pinghu, Longgang, Shenzhen Guangdong 518111, People’s Republic of China, and her present principal occupation is President Office Assistant of the Issuer.

During the five years preceding the date of this filing, neither High Power Management, nor to High Power Management’s knowledge, Ms. Ping Chen has been (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 4.

Purpose of Transaction.

Item 4 is supplemented by adding the following:

On October 29, 2019, a special meeting of stockholders of the Issuer was held. At the special meeting, the Issuer’s stockholders voted to approve the proposal to adopt the Merger Agreement by the affirmative vote of the holders of (a) at least a majority of all outstanding shares of Common Stock of the Issuer and (b) at least a majority of all outstanding shares of Common Stock of the Issuer held by stockholders other than Essence, the Rollover Stockholders, or any of their respective affiliates, officers and directors, and in each case, other than Parent and Merger Sub.

On October 31, 2019, the Issuer filed a Certificate of Merger with the Secretary of State of the State of Delaware, pursuant to which the Merger became effective. As of the effective time of the Merger (the “Effective Time”), each issued and outstanding share of Common Stock, other than shares of Common Stock held by (a) the Rollover Stockholders, or Parent or the Issuer or any of their respective subsidiaries or (b) stockholders who have validly exercised their appraisal rights under the General Corporation Law of the State of Delaware, was converted into the right to receive US$4.80 in cash without interest and less any applicable withholding taxes.

As a result of the Merger, the Company ceased to be a publicly traded company and will continue its operations as a private company wholly owned by Parent, with 1,000 shares of Common Stock outstanding (which are all directly and beneficially owned by Parent).

CUSIP No. 43113X101

Page 9 of 11

As a result of the Merger, all of the Common Stock held by the Rollover Stockholders prior to the Effective Time were cancelled, and all of the options held by Messrs. Pan, Li and Ma prior to the Effective Time were cancelled without payment of any consideration.

As a result of the Merger, the Common Stock of the Issuer has ceased to trade on the NASDAQ Global Market (“NASDAQ”) at the close of business on October 31, 2019 and became eligible for delisting from NASDAQ and termination of registration under the Act. The Issuer has requested that NASDAQ file with the SEC a Form 25 to remove the Common Stock of the Issuer from listing on the NASDAQ and to deregister the Common Stock of the Issuer pursuant to Section 12(b) of the Act. Additionally, the issuer intends to file with the SEC a Form 15 requesting the deregistration of the Issuer’s shares of Common Stock under Section 12(b) of the Act and the suspension of the Issuer’s reporting obligations under Section 15(d) of the Act.

The descriptions of the Merger Agreement and the transactions contemplated thereby set forth above in this Item 4 do not purport to be complete and are qualified in their entirety by reference to the full text of the Merger Agreement, which has been filed as Exhibit 7.05 to this statement and is incorporated herein by this reference in its entirety.

Item 5.

Interest in Securities of the Company.

Items 5(a), (b) and (c) are amended and restated as follows.

The information contained on each of the cover pages of this Amendment No. 7 and the information set forth or incorporated in Items 2, 3, 4, and 6 are hereby incorporated herein by reference.

(a) As a result of the Merger, all of the Rollover Shares were cancelled.

As of the date hereof, each of Mr. Dang Yu (George) Pan, Parent and High Power Management beneficially owns 1,000 shares of Common Stock of the Issuer, which are directly held by Parent. Such 1,000 shares of Common Stock represent 100% of the outstanding share capital of the Company. Parent, a Cayman Islands company, is indirectly controlled as to approximately 77.8% by High Power Management. High Power Management is wholly owned by Mr. Pan, and Mr. Pan is a director of High Power Management. Mr. Pan indirectly owns (through High Power Management and Advance Pride) approximately 79.5% of Parent. Mr. Pan is also a director of Parent. Pursuant to Section 13(d) of the Act and the rules promulgated thereunder, each of Mr. Pan and High Power Management may be deemed to beneficially own all the Common Stock directly held by Parent in the Issuer.

The above disclosure of percentage information, with respect to the share capital in the Issuer, is based on a total of 1,000 shares of Common Stock outstanding as of the date hereof.

(b) The powers that a Reporting Person has relative to the shares discussed herein may be found in rows 7 through 10 of the Cover Page relating to such Reporting Person, which is hereby incorporated by reference.
