In general, boil once a day, pig's feet ginger can be put at room temperature can be put at least a month.

Note tips:

1, the longer the soaking time, the better the flavor of the eggs and ginger. Eat feel not enough, you can cycle add ingredients. Anyway, just add it two days before the pig's feet are eaten.

2, if you accidentally get water inside the wok and grow mold, carefully dispose of the mold with a spoon, then re-boil and roll, and let it cool for storage.

3, if a layer of oil comes out on top of the vinegar because there is too much oil in the pig's feet, you can use the oil to beat it out and fish the noodles to eat!!!!
