Belgium is a country famous for making chocolates, and people who travel to Belgium will be attracted by the local chocolates  But for Chinese tourists who are sensible and knows the market, they will buy them only if the chocolates sold in Belgium are cheaper than the same chocolates sold at home
In fact, anyone who knows the market knows that Belgian chocolates sold in China are not more expensive than the same chocolates sold in Belgium
Chinese tourists who are irrational or do not know the market will buy chocolates in Belgium.
