[ fāpiào ]
When doing your shopping, it's generally good to get into the habit of asking for a receipt as in China, receipts are rarely just given. In China, it is the consumer's responsibility to ask for a receipt.
A fapiao in China is more than just an ordinary receipt. It is different to other countries where receipts are usually just used to record a transaction. In China it is also the way in which the government monitors the value added tax (VAT) paid on any transaction.
For the common consumer spending money in China, a fapiao can be used as valid proof of expenditure where one needs to reclaim any expenses made (e.g. on a business trip).
Sometimes foreigners are also required to provide a fapiao from rented or purchased accommodations as proof of residency for visa purposes.
