后海不是海，曾是北京古海港，现今大爷们在这游泳、钓鱼、踢毽子

北京的后海北誉为来北京必打卡之地，一直想看看北京人会去溜冰的地方长什么样。没想到只是一个小小的湖，是周围居民的公园。Beijing’s Houhaibei is known as a must-have place to come to Beijing, and I have always wanted to see what places Beijingers would go to skating. Unexpectedly, it was just a small lake, a park for the surrounding residents.
