Yuan Bai knew what was going his grandfather's head and immediately interjected " yes , yes , the price is reasonable! Compared to those greedy shopkeepers who are taking advantage of the situation and have raised the money of one metre of rice to two or three taels , they are selling their vegetables around twenty to thirty copper coins !" Yuan Bai was afraid that his grandfather wouldn't understand the severity of the situation and hastily added " their vegetables are tender and juicy , and other than them no one else is selling such green vegetables currently , give me some money grandfather , I will bring some for our family to eat !"
