Why does baby seldom speak Cantonese?

You mean Angelababy. Angelababy is from Shanghai, and she spent her childhood in Shanghai. Cantonese is not her mother tongue. Besides, it is necessary for someone to answer you when you speak Cantonese, otherwise it is no use for the other person not to understand what you say. Wong Cho Lam is a native of Hong Kong. He seldom speaks Cantonese among Ben Xiong, because other people basically don't understand it except Angelababy. It's not that he can't speak Mandarin well, so why make an extra turn? However, Angelababy always speaks Cantonese when he participates in Hong Kong TVB programs.
