The south is much wetter for the north, and the air is better. Patients with allergic rhinitis will feel more comfortable and their symptoms will be alleviated.
I come from the north, and I have severe allergic rhinitis. I can't stand my nose in winter. It feels much better to go to Wuhan, and it feels good to stay in Shanghai for a year. I suggest you go to a humid city near the sea in the south, but one thing is that there is no heating in winter in the south, which is a little unbearable. What city are you from now? It depends on your preference ~ ~
