On the mobile phone, select the word "Huawei" and select "Keyboard Settings → Traditional Input" to change the input Chinese characters into traditional ones.

On the computer, in the property settings of the text input method, just change the default state of "Common" to "Simplified" and set it to "Traditional". In program files such as Word, simplified Chinese characters should be changed into traditional Chinese characters, and the font should be changed from "Song style" or "regular script" to "Song style complex" or "regular script complex" and so on.
