The things are okay, I bought them last year; but when I placed my first order at the beginning of this year, I found that a few packages of the things were not opened properly and part of them was eaten; I called Huacheng customer service and asked to return them. When exchanging goods, the customer service attitude was very poor. They said it was our own problem or the courier's problem. They were not responsible. Even if we returned it, they refused to accept it and gave us a slap in the face. The food was no better than others, especially the vacuum bags. products, so our office staff are very angry and will never dare to buy food from Huacheng again! ! !
