Why does Japanese sound so good? . ?

Japanese pronunciation rules are very simple. There is only one high note in a sentence, which is very gentle, so it sounds good.

From the Japanese point of view, the Japanese are better than the China people.

I watched a TV program in Japan before.

It is to record the daily conversations of various countries and listen to them in the street, so that they can guess what is said in the recording.

I remember when I heard the Chinese version, most Japanese people said it was a quarrel. . .
