A long time ago, there was a game called "Wow Ya Ya", but now I can't find it on the Internet. I remember this pronunciation, but I can't remember the words clearly.
wawayaya, through computer games, let children learn some knowledge, including pinyin, language, mathematics, art, music, science, society, etc. The grades are 1-3 years old, 3-6 years old, 4-9 years old, etc. There is no such dish for sale in the market. You can find it online, and my son has played it. Now he has grown up and given it away.
