黄牛赞终生从教乐而复，春蚕虽老意自舒。几支白笔犁田垄，一块黑板绘新图。头上银丝根根露，额前年轮条条出。最是开心灯下读，笙歌曼舞总不如。一生拉车不计酬，风吹雨打无怨尤。夕阳知晚四蹄奋，鞠躬尽瘁老黄牛。春蚕颂(外一首)@于广生 Ox Chan like life from the music and complex, although the old spring silkworms since Shu. Several white plows furrows, a blackboard painted new map. Head silver root root dew, the amount of years before the strip out. Reading is the most fun lights, singing and dancing are not as good. Life does not count the car pull, wind and rain do not blame especially. Evening Sun know the four hoof Fen, spared no efforts in the old ox. Spring silkworm ode (outside one) @ Yu Guangsheng
