I spent ten days back in Chengdu. I had two intense drinking sessions in the last three days, and my body needs rest. December is already halfway over; everyone's busy, but as usual, we all get together at the end of the year. The air quality in Chengdu hasn't been great lately. My air purifier runs 24/7, but the effect is limited. My allergic rhinitis has flared up a lot recently; I often wake up in the middle of the night and have to get up to rinse my nose with saline solution before I can fall back asleep. The lack of rest has given me dark circles under my eyes. So, it's time to leave; it's time to go somewhere warm and relax.
