最近，苏大爷老两口被儿子接到重庆市渝中区小住。闲着无事，偶尔也到农贸市场帮助买点菜。苏大爷是重庆市荣昌县清流镇的农民，种菜是他干了30年的老行道。他发现众多城里人有个怪习惯，买菜时喜欢挑菜叶黄瘦、遍布虫孔的蔬菜。一问才知道，城里人认为，有虫孔的蔬菜可能没喷? Recently, Grandpa Su and his son received a small living in Yuzhong District, Chongqing. Nothing else, occasionally to the farmers market to help buy some food. Grandpa Su is a farmer in Qingliu Town, Rongchang County, Chongqing. He planted vegetables for 30 years. He found many people in the city have a strange habit of buying pick vegetables like pickle yellow thin, all over the wormhole vegetables. I asked to know, the city people think that there may not spray wormhole vegetables?
