Ordinary shares financial
"Ordinary shares, par value US$0.000025 per share"
Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.
BVI business company financial
"ordinary shares held by Securingium Holding Limited, a BVI business company"
A BVI Business Company is a legal entity formed under British Virgin Islands law that acts like a lightweight, flexible corporate container for holding assets, running operations, or owning subsidiaries. Investors care because it offers limited liability, simple setup, and tax-neutral treatment—similar to using a safe, portable box for investments—while also raising questions about transparency, regulatory oversight, and cross-border compliance that can affect risk and valuation.
Limited Partnership financial
"owned by Changchun Feier Investment Center (Limited Partnership)"
A limited partnership is a legal business structure with two types of partners: at least one general partner who runs the business and bears full legal responsibility, and one or more limited partners who contribute money, share profits, and have liability capped at their investment. For investors, it matters because it separates control from financial exposure — like putting money into a store without managing it — and affects how returns, risks, taxes and transferability of ownership are handled.
trustee financial
"100% owned by Trident Trust Company (HK) Limited as trustee of Generations United Trust"
A trustee is a person or institution legally appointed to hold and manage assets or enforce an agreement on behalf of other people (beneficiaries). Think of a trustee as a neutral referee or custodian who must act in the beneficiaries’ best interests, follow the trust or contract rules, and handle distributions, recordkeeping and enforcement. Investors care because a trustworthy trustee protects their rights, ensures promised payments or remedies are delivered, and can influence recoveries if things go wrong.
settlor, beneficiary, and protector financial
