It depends on the weather. It's best not to eat for a day or two in hot weather, and you can put it for a few more days in cold weather. However, citron tea, which has not been refrigerated for a long time, should try not to drink it, which is likely to go bad. If you can't eat it all at once, you can consider buying it in bags. We sell it in citron tea, put it in a bag and put it in a vacuum. One or two bags at a time is enough, and there is no waste. You can buy a small amount to try. Hangzhou Xia Guo
