Quite interesting. I originally wanted to participate in the essay contest of Little Sapling to see if I could sign a contract. It's a pity that children's literature must first pass face verification before it can be displayed, signed up, and tested to see if it can be signed. One person per day, a total of three verification opportunities. I failed. The signing failed, and the face verification also failed. Hey, forget it, this article will continue to be updated. If another article can be signed, it can be displayed. The day this article was published was when I signed the contract. What a "deviation from the original intention".
Purpose: Be a great detective.
