Common traditional Chinese characters should be remembered. I don't know what position you are facing now and what style you are studying. It's best to start with regular script. Generally recommended contact order is Liu Ti, Yan Ti, Ou Ti and Zhao Ti, followed by running script and cursive script. Of course, you can also choose to belong to Weibei, and the practice of Weibei can start after European style. The two scripts are very similar, but the amounts seem to be far apart.
If you want to remember traditional Chinese characters, you should practice and read more. Different fonts have different ways of handling glyphs. For example, the mysterious pagoda in Liu Gongquan has a clear font and is very suitable for beginners. For the characteristics of different fonts, you can visit my space.
It should be noted that simplified Chinese characters and traditional Chinese characters cannot be mixed. It is ok to simplify them all, but few people do.
