 # Tip
 
 Cài thêm font chữ Mengshen ([hướng dẫn ở đây](https://catusf.github.io/posts/S%E1%BB%AD-d%E1%BB%A5ng-font-ch%E1%BB%AF-c%C3%B3-phi%C3%AAn-%C3%A2m-Pinyin/#2-t%E1%BA%A3i-font-v%C3%A0-v%C3%A0-s%E1%BB%AD-d%E1%BB%A5ng-n%C3%B3-%C4%91%E1%BB%8Dc-tr%C3%AAn-app) ) vào máy thì xem phụ để tiếng Trung mà có Pinyin ở trên có thể giúp nhớ cả mặt chữ.
