There are great cultural differences. Although it has been more than 20 years since China and Hong Kong returned to the motherland in 1999, China and Hong Kong have been colonized for nearly a hundred years, with great cultural differences. At present, the culture of Hong Kong is still deeply influenced by colonial culture, as can be seen from the movie posters. Lawyers in Hong Kong still wear wigs. Hong Kong people are used to this brand of colonial culture, while mainlanders are not so comfortable.
