Ma Lexin: happy heart; happy heart. Suitable for boys and girls to choose names. From "Book of Rites and Music": "Therefore, those who are moved by sadness will have their voices quivering to kill; those who are moved by joy, their voices will be moaning and softened."

Warm reminder: When choosing a name It is not advisable to use words that sound "tongue-twisting"; sometimes you can use overlapping sounds when naming. For example: Ding Ding, Fang Fang, Xin Xin, etc. If the name is not an overlapping sound, there must be a certain distance between the pronunciation of the first name and the surname. Otherwise, it will not be read smoothly and the desired effect will not be achieved. Some names are difficult to pronounce and difficult to pronounce, and they may be mispronounced or misheard. The reason is that the words used in the names are difficult to pronounce.
