Tips:
1. The water in the pressure cooker will not evaporate too much, so the amount when adding water is a little more than that of drinking;
2. Boiled wolfberry for a long time will destroy its nutritional content, so put it at last;
3. Ginkgo can not be eaten raw, cooked food can not be over-eaten, especially small babies.
