I have never drunk 70%, and I have drunk both 50% and 100. There is indeed some difference, but my menstruation family only drinks that 50% for years. The most important thing is that my uncle hates drinking white water. He wants to drink that kind of strong tea. When I live in his house, I will follow it. It's good, it's really fragrant ~ ~ If you buy it, The room is full of fragrance. Actually, your father is very happy to see you take things home. Besides, if your father is not very fond of tea and doesn't have too high requirements for tea, 50 will be fine. Your mind is very important.
When you get ahead in the future, it's not too late to buy expensive ones. You can do as much filial piety as you can, and your father may not be happy with "filial piety" beyond your ability.
And this thing of tea, alas, is not my nagging, it is really not the most expensive, only more expensive!
