In various existing writing methods, these two characters are the same in the right half, but in fact, there are two ruzi on the right side of Shaanxi traditional Chinese characters and two ruzi on the left side of Xia traditional Chinese characters. Strictly speaking, it is not the same, but when writing seal script, people and Confucianism are indistinguishable, and Xia characters in Chinese character interpretation are also written according to the small seal script of Shaanxi characters. Therefore, when writing Xiao Zhuan, these two words can be written the same.
