In fact, although many people know that bird's nest can have great benefits for our human body, and it is good to eat bird's nest regularly, it does not mean that everyone has sufficient control over the storage of bird's nest. Many people even think that things like bird's nest are all dried and solved after buying them back, and they can be stored for a long time, so they don't have to worry about it at all, in fact, is it just like that?
