It is a well-known fact that/what the faces some people show to the world might be completely different to their real personalities. For instance，most comedians have permanent smiles on their faces and always sound cheerful because that’s the nature of their work. From this，it’s impossible to know what/where their true feelings are. Although they might be laughing on the outside ，they might be crying on the inside.

In 2018, Ma donated her entire life savings to her home town in Mulan County. This donation was to support local education and public welfare.
