I want to go to Hongshan Army Racecourse and play differently with Ulan. Is it cold?

Just got back from there, and it was a little cold after sunset. If you come out at night, adults can wear long sleeves, coats and pants. Children should wear thick clothes, and it is best to add velvet to their coats. It's fine during the day, so you should protect yourself from the sun. For sun protection, adults and children should also wear long-sleeved trousers and sports shoes during the day. I arrived at the military horse farm on the 8th, so I came back 10 because the child was not feeling well. I want to stay one more day, this season is just right, the grass is more beautiful!
