To open a bookstore on Taobao, you need to apply for a business license and a tax registration certificate, which are the basic documents for conducting any business activities. At the same time, because books are cultural products, you also need to apply for a cultural business license. In addition, for imported books, you also need to apply for an import publication business license. Finally, the bookstore also needs to open a bank account and conduct relevant financial management to meet tax and financial requirements.
