The reason why Didi Electronic Invoice is reopened is because the central warehouse and processing center of Didi Electronic Invoice is located in Kunming, Yunnan, so Didi will also reopen Yunnan Electronic Invoice to ensure the rapid processing and timely uploading of invoice information. The advantage of this is that it can speed up the processing of invoices, and at the same time it can avoid tax risks and disputes caused by regional differences. There is a certain difference between the reopening place and the issuing place of Didi electronic invoice. According to the regulations of State Taxation Administration of The People's Republic of China, People's Republic of China (PRC), electronic invoices must be issued and uploaded on the system of the tax authorities where the buyer is located or where the business is located.
