Take your little buddies to Orson for a turn, pass by the Bird's Nest and take a look at the Bird's Nest, Water Cube, Olympic Sports Park and Olympic Forest Park. They are all trained in clusters. They are all on the Line8 subway, walking about two or three kilometers from the Olympic Sports Park (which has the Bird's Nest Water Cube Tower or something)? There are small pavilions on both sides of the road, but the trees are too few or very sunny. [Ticketing] Both the Olympic Park and Olsen are free, but there's a charge for entering the Bird's Nest and the Water Cube (it seems not cheap), so I don't remember how much we missed the time. I went to the Bird's Nest in 2008. The whole building is very special, but there is also a stadium inside. Bird's Nest, Water Cube, these are landmarks, but in the past eight years, under the devastation of Beijing's weather, they all feel a little grey and old. You can also see huge torches and championship walls and so on. The venue is very large with a handful of uncles who play roller skating. There is also a New Austrian shopping mall. You can buy souvenirs or something. It's worth visiting for visitors to Beijing. Catching up with the fine weather on that day, I think the clouds look better than the bird's nest
