Where should I buy souvenirs in Changchun? I compared prices at tourist attractions and supermarkets.

This is a question worth answering carefully because Changchun's souvenir market has a unique phenomenon: the same local specialty can have two different prices and two different qualities in areas near tourist attractions and in local supermarkets. People visiting Changchun for business or tourism often only have one or two days to buy souvenirs, and if they buy the wrong ones, the gifts they bring back will be neither tasty nor suitable as gifts. This article does not provide a recommendation list, but only a comparison, clearly explaining "where to buy, how to distinguish between them, and which option to choose in different situations."
