Now in Hanoi, I want to buy some Vietnamese specialties to return to China, which are meaningful and convenient to carry. Where to go and what to do in buy buy?

Actually, you don't have to go to that specialty store to buy things. It's very expensive and it's very expensive. You can know in advance what special products to buy, and then you can buy them in a nearby supermarket (there is a big supermarket called Big C near my place, which is opened in France and takes a taxi from the city center to about 7, VND), coffee, mung bean cake, dried jackfruit and perfume. The price is also a civilian price, clearly marked, not expensive! As for perfume, Miss Saigon is famous in Vietnam, but it is mainly sold in Ho Chi Minh City. I suggest you buy it in Ho Chi Minh next time.
