1 I feel china is way more noisier. I couldn’t hear phone ringing a lot there. The day I back I felt how quiet it was. Like birds lChinese might have to increase volume.
2. Myself is a loud talker, I try to lower, but it’s still work in progress. So I can relate to those loud talkers. But definitely I am more conscious now in public places, not just talking, but many issues like body odors, breath, dress and appearance, once again still work in progress.
So maybe we could all try gently remind others in those situations.
