The most difficult Chinese word to write

This word is the most difficult word in Chinese, and even the input method is rejected, so we have to show it with pictures. When this word is pronounced biang, it has two tones: rising tone and falling tone, that is, two or four tones. A ***57 painting. A special face of Xi, biang biang face. Hahaha, experience it yourself! ! ! I once saw a joke that a pupil's parents gave his son three complicated words, and the child cried during the exam, crying badly! Someone else has been doing the problem for a few minutes, and his name has not been written yet! )
