After the reunification, the mainland helped Hong Kong economically. For example, during the Asian financial turmoil, it was difficult for Hong Kong's economy to restore stability immediately without the support of the Mainland. I believe Hong Kong people must be very grateful for this. However, in terms of democracy, freedom and the rule of law, it seems that the mainland has not given much support to Hong Kong. It seems that there are many restrictions and many patterns. Some Hong Kong people are dissatisfied. They always make trouble in parliament and take to the streets, which is very disharmonious. These, I suggest the landlord investigate and write a paper to let everyone know.
