One country two systems----- Hong Kong is a region of China, but it shares different systems, Hong Kong practice the capitalism while China is communism.
Hong Kong people govern Hong Kong----- China gives high (automatic) =高度自治 for Hong Kong people to govern Hong Kong. China will not take charge in Hong Kong affairs directly. And this situation will be unchanged for 50 years.

One country two systems is a policy set by Mr. Dang Xiao Ping, it was not set for Hong Kong, but for Tai Wan. However, Tai Wan refused to cooperate since there was no sample. So, China turned and set this policy to Hong Kong to settle problems and set an example to Tai Wan.
