Venture capital companies sincerely support and help inventions and innovations. It's just that inventors are afraid of technology leakage and are unwilling to show investors key technologies. Inventors just want others to invest money blindly, and investors are not allowed to ask about other things. Others hold a picture of a castle in the air and say everywhere that no one knows the goods and no one invests.

Somebody else's Watt wants to show investors a small core experimental device, and investors will invest. Quite a few inventors are unwilling to take the risk of technology leakage, so most of China's major inventions in modern times are kept secret by inventors.
