It is generally difficult to obtain the undisclosed financing details of a startup and may involve illegal or unethical behavior. Such undisclosed information is a company's trade secret and is strictly protected. Unauthorized attempts to obtain it may violate laws and regulations, such as the provisions of the Criminal Law of the People's Republic of China on the crime of infringing on trade secrets, and also violate business ethics and industry norms. Formal sources of information are mainly voluntarily disclosed by the company, or obtained through legal news reports, public channels, etc. after its public financing.
