All these must be harvested at the best time to get the best wild vegetables. Wild vegetables grow and develop for one year and many years, but their eating places may become old and withered in a short time, no longer suitable for eating, or their taste will decline, as is the case with chicory. City people are willing to pay a high price to buy it back to eat, which is convenient for clearing the stomach.
