Mainland investors can buy Hong Kong stocks through Shanghai-Hong Kong Stock Connect or Shenzhen-Hong Kong Stock Connect, but they need at least 500,000 investors to buy and sell. If you can't meet the requirements, you can also buy and sell some funds that invest in Hong Kong stocks and indirectly buy Hong Kong stocks.

Or investors can open an account with a securities firm that supports Hong Kong stock trading, and after applying for opening an account, they can purchase Hong Kong stocks normally, such as Tiger Securities and Xue Ying Securities.
