Potato and Onion are good friends. One day Onion laughed at Potato for being rustic and having the word "Ru" in his name. Little Potato got angry and ignored Onion.
One day Onion saw Potato coming over and called him Little Potato, Little Potato. Little Potato glared at Onion and said that I changed my name, my name is Yangtao.
In fact, biologically speaking, potato is also called potato.
