It's the solar term in Grain Rain. Every year during the solar term in Grain Rain, sweet potatoes will be planted. Before the villagers go out to work, every family will be busy planting sweet potatoes in the fields. Because at that time, the scale of sweet potato cultivation was relatively large, not only people had to eat it, but also livestock had to eat it, and a large part of sweet potato was also used to process it into agricultural and sideline products to sell money, such as sweet potato powder and sweet potato vermicelli. Nowadays, few people in the village grow sweet potatoes, and even fewer people make sweet potato vermicelli. I still make some at home every year. I made more than 200 kilograms of sweet potato vermicelli the year before last, and nearly 400 kilograms last year.

None of these were sold in the market, all of them were twelve yuan a catty, which made people buy them all.

As the old saying goes, "cheap is not good", although the price of sweet potato vermicelli in supermarkets is cheap, compared with the sweet potato vermicelli made by farmers themselves, although the price has advantages, the taste and nutrition will be greatly reduced.

So it makes sense to get what you pay for.
