The information set forth in Item 3 of this Schedule 13D is incorporated herein by reference. The Reporting Persons acquired 62,367,293 Class A Ordinary Shares (including Class A Ordinary Shares represented by ADSs) prior to and in the initial public offering of the Issuer. The Reporting Persons previously reported their beneficial ownership of these Class A Ordinary Shares on Schedule 13G, and are now filing this Schedule 13D in connection with the Competing Proposal (as defined below) described in Item 4 below. On January 6, 2025, the Issuer announced that it had received a preliminary non-binding proposal letter, dated January 5, 2025, from Trustar Mobile Charging Holdings Limited, Mr. Mars Guangyuan Cai, Mr. Peifeng Xu, Mr. Victor Yaoyu Zhang, and Ms. Maria Yi Xin (collectively, the "Consortium"), to acquire all of the outstanding Shares that are not already beneficially owned by the Consortium for a proposed purchase price of US$0.625 per Class A Ordinary Share or US$1.25 per ADS (the "Current Price") in cash (the "January Proposal"). Subsequent to the January Proposal, on February 12, 2025, the Reporting Persons, the second largest shareholder and long-term investors of the Issuer since 2017, delivered a letter (the "February Letter") to the board of directors of the Issuer expressing their fundamental disapproval of the January Proposal, citing that the Current Price substantially undervalues the Issuer and raising concerns about the circumstances surrounding the January Proposal and the independence of the special committee of the board of directors of the Issuer (the "Special Committee"). Thereafter, the Reporting Persons had a few sporadic conversations with management members regarding the January Proposal, but the Special Committee and its advisors did not engage with the Reporting Persons at all. On August 1, 2025, the Issuer announced that it had entered into a definitive merger agreement (the "Merger Agreement") with the affiliates of the Consortium, pursuant to which the Issuer will be taken private at the Current Price, implying an equity value of the Issuer of approximately US$327 million (on a fully-diluted basis). The Merger Agreement did not address the concerns raised, or include the safeguards proposed, by the Reporting Persons in the February Letter. Deeply incensed by the grossly inadequate merger consideration and the disregard for the interests of the public shareholders, on August 13, 2025, HIM submitted a competing proposal (the "Competing Proposal") to the Special Committee to acquire all of the outstanding Shares and ADSs not already beneficially owned by the Reporting Persons (other than the Shares and ADSs held by management members which will be rolled over) for US$1.77 per ADS or US$0.885 per Share (the "Purchase Price") in cash (the "Proposed Acquisition"), which values the Issuer at approximately US$450 million (based on the total number of outstanding Shares and ADS and not including options or other equity-based awards). The Purchase Price represents a premium of approximately 42% over the Current Price. The Reporting Persons expect to fund the Proposed Acquisition solely through investment funds managed by the Reporting Persons and their affiliates, and no third party equity or debt financing is required. The Reporting Persons believe the Competing Proposal offers superior value and greater deal certainty to the Issuer's shareholders and therefore constitutes a "Superior Proposal" under the Merger Agreement. References to the Competing Proposal in this Schedule 13D are qualified in their entirety by the text of the Competing Proposal, which is attached hereto as Exhibit 1 and incorporated herein by reference. The Proposed Acquisition may result in one or more of the actions specified in clauses (a) to (j) of Item 4 of Schedule 13D, including, without limitation, the acquisition of additional securities of the Issuer, a merger or other extraordinary transaction involving the Issuer, the delisting of the ADSs and the Class A Ordinary Shares from the Nasdaq Capital Market and the Class A Ordinary Shares becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, as amended. The Reporting Persons intend to continuously review their investment in the Issuer, and, notwithstanding anything contained herein, the Reporting Persons specifically reserve the right to change their intention with respect to any or all of such matters. The Reporting Persons and their affiliates may in the future take such actions with respect to its investment in the Issuer as it deems appropriate, including, without limitation, exchanging information with the Issuer or other third parties; proposing changes in the Issuer's operations, management, board of directors, governance or capitalization; acquiring additional securities of the Issuer or disposing of some or all of the securities beneficially owned by it, in public market or privately negotiated transactions; entering into financial instruments or other agreements that increase or decrease the economic exposure of the Reporting Persons with respect to their investment in the Issuer and/or otherwise changing the Reporting Persons' (or their affiliates') intention with respect to any and all matters referred to in Item 4 of Schedule 13D. The Competing Proposal and the Proposed Acquisition are subject to the execution of definitive agreements mutually acceptable to the Issuer and HIM and its affiliates.
