Is the child's method of chanting Buddha breathing in and out?

No, if you recite Buddha at the speed of Mr. Tong, you should take a breath and recite a Buddha's name. After reading the word "Buddha", take another breath, read four more words, and so on. Mr. Tong's method of chanting Buddhism focuses on reading clearly, listening clearly and listening without interruption, but breathing is secondary.

Read a Buddha's name or a word when inhaling, and another Buddha's name or a word when exhaling. This is the breathing method of a stubborn Buddhist.
