Wang Rong is seven years old. He tries to travel with other children. Look at the many branches of Li Shu on the roadside. Children will scramble to get them, but they won't move. People asked him and replied, "There are trees by the road, but there are many seeds, which will make plums bitter." Take it for granted Wang Rong often played with children when he was seven years old. I saw a plum tree bearing many plums by the roadside, and all its branches were crushed. All the children went to pick plums except Wang Rong. Someone asked him why he didn't pick plums. Wang Rong replied, "This tree grows by the roadside and has many plums. It must be bitter plums. " Take it off and taste it. It really is.
