I found that grape cultivation is really too common now, that is, in the stalls of uncles and aunts who buy food in the bazaar, purple grapes are piled up, which are sweet and inexpensive. In fact, they are all planted by their own villagers and sold to vegetable vendors, who then sell them to people who come to buy food in an endless stream. I bought it too. Sweet and delicious, the price is not expensive at all.
