It might be called the National Day, denoting one day. But no, in China it's celebrated for seven days in total in the Chinese mainland. Hong Kong celebrates it for one day and Macau for two. Whichever celebrations you partake in, you are sure to have a memorable time! There is no doubt about that. Besides, you need to book accommodation in good locations for the celebration. For one, you can look into Tianjin serviced apartments, the likes of Ascott TEDA MSD Tianjin, for a good experience.
