How to write a "typo joke" at the beginning of the composition?

Chinese characters are extensive and profound, and each word has its own specific pronunciation, meaning and strokes. If you write Chinese characters wrong, it will not only defile the purity of Chinese characters, but also make people feel confused and ironic.

I remember that embarrassing thing happened one day in the summer vacation of grade three. ...

There were no clouds in Wan Li that day. I just finished my homework and wanted to write a letter to my cousin. After writing the letter, I wanted to write "Don't fold" on the envelope, but somehow I wrote "Don't open". After the letter was sent, I waited for my cousin's reply with great joy.

The content in the reply made my mother and I wonder, cousin, I haven't seen you in January, but I didn't expect your Chinese level to drop sharply! If I don't know you, no one dares to touch your letter! I quickly called my cousin to ask him what was going on, but he just smiled and hung up. A few days later, I received another letter from my cousin. I opened the letter and found an envelope that I sent to my cousin. The striking two Chinese characters on the envelope-"Don't open it" made my mother laugh and my face became hot. "Laughing makes my stomach ache, hahaha!"

"Oh, stop laughing!"

"This joke is your own creation. Don't laugh! "

I am speechless. ...

This experience made me understand that Chinese characters are sacred characters in our motherland. If you want to learn Chinese well, you must use and write Chinese characters correctly and try to prevent typos, otherwise you will make a joke and find yourself embarrassed!
