Let me explain first: H shares, also known as state-owned shares, refer to foreign shares registered in the Mainland and listed in Hong Kong. (Because of the initials of Hong Kong -Hong Kong, it is called H shares. H-shares are physical shares, and the "T+0" delivery system is implemented, with no price limit. Institutional investors in China can invest in H shares, while individuals in Chinese mainland cannot directly invest in H shares at present. In Tianjin, individual investors can set up a "through train service for Hong Kong stocks" in the branch of Bank of China to directly invest in H shares. However, the State Council has not yet opened the floodgates for this business. It will take time for individuals to directly invest in H shares. International capital investors can invest in H shares.
I'm also a student, and I also trade stocks. I don't think your idea is practical. There are restrictions on individuals investing in Hong Kong stocks, and not everyone can. There is no limit on the price of Hong Kong stocks, and the risk is relatively high.
If you really value the intrinsic value and growth of China Mobile, I suggest you wait. It is said that China Mobile will return to A shares. Of course, the specific time is still far away.
