The green vegetables that southerners refer to refer to vegetables with green leaves. If there are no green vegetables on the dining table of southerners, it feels like an incomplete meal. Whether it is a family gathering or a banquet with guests, as long as it is a relatively sumptuous banquet, there will definitely be a plate of green vegetables on the table, either stir-fried or boiled. The bright green leaves stand out among the big fish and meat, and are specially used to neutralize and relieve greasiness.
