The weather in Yanji for a month

I'm going back to Yanji on National Day. Mom said Yanji National Day should wear long pants and long sleeves. Yanji has a great temperature difference in the morning and evening, so sandals and shorts must not be worn. You can bring a few pairs of trousers, thin long sleeves and one or two short sleeves (especially indoors) and a coat. The coat should not be too thin. The wind in Yanji is very cold. After all, it is the northeast. Some people who are particularly afraid of the cold also wear long pants on National Day. I also prepared these clothes, I hope it will help you!
