At that time, there was a great scholar named Ding Jingshen, and Zhang Yitang wanted to worship him as a teacher. When he first went to his master's school, he went to the teacher's house with a big cloth bag behind him, which contained gifts for the teacher. He put down the heavy cloth bag and held out two big pumpkins from it, each weighing about ten kilograms.
