Why is the middle of Yang Yang International Hotel hollowed out?

What I want to ask is why the center of Yang Yang International Plaza where Yang Yang International Hotel is located is hollow. Because the design of Yang Yang International Plaza is a brand-new IBIH (organic integration of independent residence and independent business) space concept, through the plaza economy and hotel-style services, the independent residential area composed of apartments and houses and the independent commercial area composed of offices and businesses will be organically integrated, which will provide the maximum diversified and convenient space for residence and office.

Blocks A and D of Yang Yang International Plaza are residential buildings, while Block C is an apartment building, which is an independent residential area. The office and the bottom business department of Block B are divided into independent commercial areas. These two parts are organically connected through air corridors and organically integrated through hotel-style services. In two interrelated but independent spaces, the advantages complement each other and support each other to meet the different needs of home buyers.

Yang Yang International Hotel, located in Zhuque Road, Xi City, is a five-star hotel with superior geographical location and convenient transportation. All kinds of luxurious rooms with super large area are equipped with computers, LCD TVs, refrigerators, safes, ironing machines, automatic mahjong tables and other facilities.
