It may be related to the fact that the cabbage is fried and bitter.

If the bought cabbage is left for too long, it will cause serious water loss, which will make the leaves of cabbage look rough and have no crisp taste, and at the same time lead to bitter taste of fried cabbage.

Therefore, it is best to eat cabbage in time after buying it back, otherwise it will not only lead to nutrient loss but also affect the taste if it is left for a long time.
