With the changes of the times and the development of the industry, Xixi Street is moving towards the goal of Hangzhou's commercial core area at a high speed. Xixi is not only located in the center of Hangzhou, but also the core area of Huanglong International Business District, which is a comprehensive business concentration area integrating commerce, residence, humanities and education. Huanglong International Business District is now the first international business district in the province and the first-class international business district in China. It is a gathering place for high-grade houses and high-grade office buildings. High-grade residential buildings in Xixi area alone include Ma Yin Apartment, Huadu Lanting Apartment, Chongwen Apartment, Baidanghai Family, Jindu City Core Building and other high-grade office buildings, including World Trade Center, Liyuan Building, International Garden, Ningbo Building, Ricky Building, etc. Each office building has its own uniqueness. In particular, the Regent World Trade Center Europe and America (EAC), which is currently on sale, introduced the international 5A standard to commercial buildings in the Yangtze River Delta for the first time, that is, the A-level building brand, A-level geographical location, A-level customer level, A-level service brand and A-level hardware facilities, which is also the latest connotation of international office quality in the world. In addition to the highlights of the Regent World Trade Center in Europe and America (EAC) currently on sale, high-grade office buildings such as Liyuan Building and Kai Tak Plaza under construction will also add new highlights to Xixi Street and Huanglong Business Circle. With the relocation of Xixi Campus of Zhejiang University in the future and the transformation of the old city in the old community, a number of high-grade commercial buildings will be added in the area. These buildings will bring new business opportunities and vitality to the vigorous development of streets, and will also become the key areas for the core of Huanglong International Business Circle to move northward.
