Quality, factory problems, and the processing process lead to high and low tea prices. Online products may not be completely correct. Now there are too many counterfeit goods, so you should see if they are exactly the same as yours. Generally, we can know their quality by drinking tea, smelling it and drinking it. Generally, we can almost tell the difference from the smell. It is hard to say clearly here, and you don't understand. I suggest you don't throw it or drink it. ! When grandpa asks, say it's delicious, just to make the old man happy, but I suggest you find someone who knows tea as soon as possible to actually identify it. If it's a fake, tell grandpa not to drink it quickly. The old man can't afford to be hurt. If your grandpa likes tea again, and you are filial, go to the tea shop yourself or find a good friend to buy some really good tea for grandpa to drink. At the same time, you can help you know about tea through your friends. Tea is very interesting. !
