Why is Qianmen Hotel also called Beijing Qianmen Jianguo Hotel?

Qianmen Hotel was a single hotel before the founding of the People's Republic of China, and it was one of the eight largest hotels in Beijing. It's called Qianmen Hotel, just like Chongwenmen Hotel and Xuanwumen Business Hotel. Jianguo brand was introduced in early 2000, so it was renamed Qianmen Jianguo Hotel and managed by Jianguo Management Company. At present, it belongs to BTG Home Inn Management Company and belongs to high-end brand hotels. But the old people in Beijing, the old employees in the store and the regular customers are still used to calling Qianmen Hotel.
