What is the source of the typo?

There are subjective and objective reasons for the appearance of typos. Typos, as the name implies, refer to words such as typos. Other characters were also called "white characters" in ancient times. The so-called "Mr. Bai Zi" is a person who often reads or writes typos. Subjective reasons are not paying attention, not reading carefully, not writing, not looking up the dictionary, being careless and sloppy.
