Xiwuqi yoghourt

Herdsmen generally don't like to drink fresh milk, but prefer yogurt. There are two ways to make it: first, pour fresh milk into a large pot and let it cool, so that it will ferment and produce sour taste; The other is to put fresh milk in the sun or in a place with high temperature, so that it will become yogurt when heated.
