Two and a half days are a little nervous. I wonder if you like more fun or more natural scenery?
If the smog is not serious, you can go to Shenzhen Bay Park Greenway in Shenzhen Bay Gymnasium, and then have dinner at Happy Coast.
It is absolutely necessary to spend a whole day in OCT East. Personally, I don&;t. ; I don&;t think it amp It is necessary to stay there. There are too many places to live in Shenzhen, and the one on Shennan Avenue in oriental ginza is good.
If you go to a bar, you can go to SeaWorld or shopping park. It S crowded and busy here, but many bars sell fake wine.
Now that the weather is not cold, they personally recommend seeing the night scene of Shenzhen, especially the whole Shennan Avenue. The roadside is green, the buildings are new, and the lighting effect is good.
And splendid china Happy Valley. You can go there if you like.
