Do the visas of the six provinces in China really need to be strictly checked?

A lot of information shows that the Canadian Immigration Department has a secret map to "take care of" applicants from six provinces and one city in China.

According to the confidential documents of the Canadian Immigration Department, the Immigration Department has drawn a map of China. According to the risk classification of provinces applying for short-term visas to Canada, six provinces including Liaoning, Hebei, Henan, Hunan, Fujian, Guangdong and Tianjin were listed as high-risk areas last year. The document also advises visa officers that applicants from these high-risk areas should be inclined to reject their applications if their application conditions are at the border.
