You can choose according to your family's taste and your own financial situation. Sichuan's old-fashioned bacon is quite good, as well as sausages, Leshan sweet-skinned duck, Nanxi dried tofu, beef jerky, Qingchengshan milk wine, pickled vegetables, and spicy tempeh.
All of these are possible. It is recommended that you go to Wuhou Temple Heng Street to have a look. They are all selling Sichuan specialties.
