The clerk who bought the book at Xinhua Bookstore didn't give the invoice, so the book was bought by mistake. Can I exchange it?
Can change. Xinhua Bookstore is a state-owned book distribution enterprise in People's Republic of China (PRC). When readers buy books in this bookstore, if they buy the wrong books, they can return them with the purchase voucher, so they can exchange them without invoices. Xinhua Bookstore is state-owned, with distribution outlets all over the country.
