The environment is ok, and the warm air is too hot. The sound effect is average, but one of the microphones is still in poor contact and the sound is intermittent. Otherwise it's noise.

The configuration of the song is also incomplete. Many songs can be found in the singer's selections, but not in the pinyin selections. Just so-so.

The equipment is average, there are no new songs, and the update status is not clear.

It feels good, but the songs are updated slowly, and some songs are not available yet, so the sound effects should be strengthened.

The environment inside is ok, and the lighting and influence effect are average. Those who pursue high quality may feel that the effect is relatively poor.
