• Limitations on director and officer liability and indemnification of our Company’s officers and directors by us may discourage shareholders from bringing a lawsuit against an officer or director.
• Our management has limited experience managing a public company.
• We may have difficulty establishing adequate management, legal and financial controls in the PRC.
• Risks Related to Doing Business in the PRC
• Changes in United States and China relations, as well as relations with other countries, and/or regulations may adversely impact our business, our operating results, our ability to raise capital and the market price of our shares.
• The operations of our subsidiaries in China, as well as our financial operations in the U.S. to the extent that they affect our subsidiaries in China, will be subject to a high level of control by the national and provincial bureaucracies in the PRC. Exercise by government authorities of that control could significantly interfere with our ability to conduct our operations in the best interests of our company and its shareholders, which could cause the value of our common stock to decline and limit or prevent our efforts to finance the operations of our Chinese subsidiaries.
• The government of China will make a direct intervention into the operations of a China-based company and take control of its operations or significantly restrict its operations if the government believes such action is in the best interests of the Chinese nation.
• Failure to comply with any PRC laws and regulations may adversely affect our business, investments and results of operations.
• Changes in the policies of the PRC government could have an adverse effect on our business.
• Uncertainties with respect to the PRC legal system, including uncertainties regarding the enforcement of laws, and sudden or unexpected changes in laws and regulations in China could adversely affect us and limit the legal protections available to you and us.
• PRC regulation of loans to, and direct investments in, PRC entities by offshore holding companies may delay or prevent us from using our capital reserves to make loans or additional capital contributions to our PRC operating subsidiaries.
• Because our principal assets are located outside of the United States and because all of our directors and all our officers reside in China, it may be difficult for you to use the United States Federal securities laws to enforce your rights against us and our officers or to enforce judgments of United States courts against us or them in the PRC.
• Restrictions contained in Chinese law on the ability of overseas securities regulators to collect information in China may deny investors in our Company the benefits of U.S. securities regulation.
• Governmental control of currency conversion may affect the value of your investment.
• The fluctuation of RMB may materially and adversely affect your investment.
• We may become subject to a variety of laws and regulations in the PRC regarding privacy, data security, cybersecurity, and data protection. We may be liable for improper use or appropriation of personal information provided by our customers.
• We will require the approval of the CSRS before our common stock may become listed on the OTCQB, Nasdaq or any U.S. securities exchange. If we are unable to obtain CSRC’s approval, our ability to raise capital will be limited, which would likely limit the growth of our company.
• If Longduoduo common stock becomes listed on the OTCQB or an exchange, we will be required to obtain the approval of the PRC government for a business combination, the issuance of our common stock, or maintaining our status as a publicly listed company outside China.
• Risks Relating to Our Common Stock
• We are an emerging growth company and, as a result of the reduced disclosure and governance requirements applicable to emerging growth companies, our common stock may be less attractive to investors.
• Shareholders do not have pre-emptive rights, which will cause them to experience dilution if we issue additional securities.
• We are unlikely to pay cash dividends in the foreseeable future.
• Our insiders own the majority of the outstanding shares of our stock, and accordingly, will have control over stockholder matters, the Company’s business and management.
