What's the difference between branches, representative offices, offices and subsidiaries?

Basic definition of the four: 1. Branch: branches established by domestic companies abroad are called branches; 2. Representative Office: The branches established by foreign-funded enterprises in other places are called representative offices; 3. Office: The office is actually an old saying. Since the implementation of the new company law, the industrial and commercial bureau has cancelled this statement. For example, when a foreign company comes to the Shanghai leasing office to contact business and expand the market, according to the provisions of the new Company Law, it does not need to go through any formalities at the Industrial and Commercial Bureau, and it is directly listed as "Shanghai Office of XX Company" without going to the Industrial and Commercial Bureau for any license; 4. Subsidiary: A subsidiary refers to a subordinate enterprise effectively controlled by the parent company or one of a series of companies directly or indirectly controlled by the parent company. Then, what's the difference between setting up subsidiaries, branches, representative offices and offices? As mentioned above, a subsidiary is a subordinate enterprise effectively controlled by the parent company or one of a series of companies indirectly controlled by the parent company. Branch refers to a branch of a limited liability company established in Chinese mainland, which belongs to a domestic-funded enterprise. In the national tax policy, it is often synonymous with permanent institutions; A representative office refers to an administrative unit of the government that handles affairs or a place that handles certain business or provides services. The representative office is the representative office of a wholly foreign-owned enterprise and the permanent representative office of a wholly foreign-owned enterprise in China. 7.
