Abstract:"Modern architecture" refers to the new forms of architecture that accompanied industrial production in the 18th and 19th centuries. The architectural form should satisfy the new function, utilize the new technology, and conform to the national aesthetic concept. The ethnic form has progressively become the new proposition of modern architectural creation. The ethnic form of modern Chinese architecture has experienced different stages of development. From the beginning, it is based on how to inherit the old form, convert the old form, and ultimately replace the old form with the new form.
