What is the difference between Zhao and He?

There is no difference between Zhao and He.

Both Zhao and He are pronounced "zhào".

曌: Pinyin zhào, the same as "zhao", is a word chosen by Zong Qinke a year before Wu Zetian became emperor, which means that the sun and the moon are gliding in the sky and shining on the earth.

羾: The upper part of the original character is "日月", not "目目". Since people did not dare to write the taboo of the emperor's name directly, in order to "avoid", the upper part of the character "曌" was changed to "日月". "Moon" was written as "Mou". It was not until the end of the Ming Dynasty that the "Mou" in the book "Zhengzi Tong" written by Zhang Zilie was corrected under the item "Originally from the sun and the moon, not from the two items".
