Why do Hong Kong, Macao, Taiwan and overseas Chinese retain their Chinese traditions so much better than we do on the mainland?

Because they attach more importance to the overseas Chinese because they can not return to China for a long time to keep the Chinese traditions to express their respect, as well as the love of the motherland, to return to the motherland of the hope. After all, Hong Kong, Macao and Taiwan have experienced the pain of separation from the motherland, they take the Chinese national tradition as something sacred. While mainlanders are in China, they naturally don't show too much importance to the things of Chinese national traditions
