How long can an egg roll in Yuen Long last?

Egg rolls are baked goods, and most of the water has evaporated. When they get a little cold, wow! Sweet, crisp and delicious. If the weather is fine, you can put it in the north for three days, and then put it in the north for four days, and the feeling will drop, because there will be moisture in the air on sunny days, and the crispy egg rolls will absorb the moisture in the air and gradually fade and deteriorate. In the environment with high air humidity in the south, after the egg roll is completely cooled that day, the leftovers should be sealed with thick plastic bags and eaten within one week.
