What do you mean by whole wheat and half wheat?

The difference between full-open wheat and half-open wheat.

1, fully open wheat: it means that there is no original singing in the accompaniment, only pure accompaniment, which tests the strength of the singer. 2. Semi-roasted wheat: it means that there are both accompaniment and some original songs, and the singer saves effort and the effect is better when singing. 3, no wheat: there is no difference with CD, the sound and picture are delayed, and the mouth shape does not match.
