What are the luxury hotel brands? Please give me this little white science ~

The luxury hotel brands I know are Intercontinental Hotel, Peninsula Hotel, Four Seasons Hotel, Marriott Hotel, MGM Diaoyutai Hotel and so on, but Marriott and Four Seasons Hotel are a bit like high-end chain hotels, and MGM Diaoyutai is different from them. It is a high-end hotel management platform jointly built by Diaoyutai State Guesthouse and MGM International Hotel Group. At present, the four hotels that have been opened in China have their own characteristics and are well integrated into the local cultural heritage. Personally, I think it is one of the best hotels. Besides, the hotels under MGM Diaoyutai have good locations. Some can directly see the beach and the sea, some can enjoy the lake view and river view, and some are in alleys with local characteristics. Last time I stayed at Shanghai Suning Baolijia Hotel, I could see the river view of Suzhou River and the invincible Huangpu River. The night view was beautiful. In addition, the interior decoration of the hotel is noble and elegant, modern and modern, with complete facilities and thoughtful service. The experience of staying for two days is particularly good.
