How do I know if Zhao Yaya can vacuum? Will it affect the taste? I’m traveling and want to take it back to my family

Sure, my friend from Leshan works in other provinces, and the sweet-skinned duck turned out to be too far away to come back, so I sent him the one from Zhao Yaya’s. He has this service. All he needs is I added a customer service WeChat account and sent SF Express to deliver the goods. Normally, I received it the next day. It was arranged properly and appropriately. My friend quickly tasted it after receiving it. He said it was an authentic Leshan flavor and was particularly delicious. It made him feel homesick hahaha
