“Liaoning, spent too much time in Shenyang. It’s usually a layer of soot that’s all over everything.”
My wife is from Shenyang and I know what you are talking about. The morning sky usually has a yellowish brown tint to it. She was amazed by how clean the air is here in the United States.
She only had to go to Chengdu for that but yeah, it’s a lot cleaner here. What amazed me was how well the nose acts as an air filter when it really has to. Saw how well it worked every night blowing it out in the shower, ooof.
