Real estate development refers to the general term for land development and housing construction carried out by enterprises engaged in real estate development in order to realize urban planning and urban construction (including the development of new urban areas and the reconstruction of old areas). Real estate refers to land, buildings and the inseparable parts fixed on the land and buildings and the various rights and interests attached thereto. Real estate is also called real estate in economics due to its own characteristics, namely the fixed location and immovable nature. It can have three forms of existence: land, buildings, and premises combined into one. In real estate auctions, the auction objects can also exist in three forms, namely land (or land use rights), buildings, and physical entities and their rights and interests in the integrated state of real estate. As personal property ownership has evolved, real estate has become a major component of business transactions. Buying real estate is an important form of investment. Hong Kong real estate attaches great importance to real estate Feng Shui. Zhang Jinhua, a descendant of the Celestial Master and a Feng Shui master, said: Blessed land is a blessed place for people to live in. Heaven and man are one, man and earth are harmonious, and those who are suitable are blessed.
