Why didn't Northeast Pharmaceutical have margin financing and securities lending?

The reason why Northeast Pharmaceutical has no margin financing and securities lending is because there is a risk of stock suspension. According to relevant information, Northeast Pharmaceutical is a listed company, and there is a risk of stock suspension, so margin financing and securities lending are not allowed. Margin trading requires the exchange to list the underlying stocks regularly, but Northeast Pharmaceutical Co., Ltd. has no such requirement, so margin trading is not allowed.
