I know a word, dragon, written in traditional Chinese characters. By chance, I met his second brother, Yu (Da, two sounds), which means that two dragons stand side by side, and the meaning is also very straightforward: Shuanglong, the heart of Yu, and the heart of Yu. Isn't that strange? By chance, I learned that dragons and ostriches have a third brother: Da (another two sounds), and the three dragons are stacked together, which means that dragons take off. When I thought I had collected all their homes, the fourth brother came: (this word pronounced Zhe, two sounds), yes, you are right, this word means that four dragon kings sit together and play mahjong! What a scene this is! This word means to talk a lot!
