During the Jiajing period of the Ming Dynasty, a large family was blocked in Jinan, Shandong Province, this family name is Zhang, there is a lot of land in the local area, to collect rent for a living, the local people respect him as Zhang Laoye. This old man Zhang has a son and two daughters in his family, and since he was a child, he has been very precious to this only son, and has placed high hopes on him, hoping that he can pass the reading exam to become a jinshi official, and finally be able to honor the ancestors of the family. Mr. Zhang's ancestors had never produced a reader, so he always felt that someone looked down on him because of it. Therefore, from the time when his son learned to speak, he specially invited a famous private school teacher from nearby to teach him, and the private school teacher was very serious about the teaching of Mr. Zhang's son, and he especially liked him, so he gave him a name called Zhang Yunshan, the word Jingzhi.
Although Zhang Yunshan was born in a rich family, he did not develop any bad habits, he was sincere and kind, and he was hard to learn, studied very seriously, obeyed the words of the teacher, so he made rapid progress, and when he was fifteen years old, he passed the child exam and obtained the status of Xiucai. At the age of twenty-four, he passed the township examination and was selected as a person, and at the age of thirty, he bribed the guild to pass the examination to obtain the jinshi, and ranked 90th in the second class, and was later sent to a certain county in Shanxi to do zhi county.
Zhang Yunshan took the clerk of the official department to the local zhixian and has been living in the backyard of the county, he encountered a magical thing here, and he still remembers it vividly, and he also wrote this matter down in the local county chronicle, so many local people know about it.
When Zhang Yunshan was living in the backyard of the county court, he found a huge apricot tree in the courtyard of the backyard. This apricot tree is very old at a glance, the tree is tall, the canopy is flourishing, every autumn it is full of yellow and attractive apricots, pick it and taste it, the taste is very sweet, Zhang Yunshan never thought of enjoying it alone, he always asked people to pluck the apricots on the tree, and then gave some to everyone in the county to eat, so the people in the county had great respect for Zhang Yunshan County.
One day in the following year, a very old servant who also lived in the backyard of the county court carried water to the side of this tree one day, and suddenly sighed to Zhang Yunshan: "This tree is a pity." Zhang Yunshan hurriedly asked the old servant why he said this, and the old man said, "I am good at diagnosing and treating the disease of the tree, and this tree has a disease, so please allow me to diagnose and treat this tree." Zhang Yunshan was curious, he had never seen anyone who said he could treat the tree before, so he agreed to his status request.
The old servant then examined one of the trees and said, "This tree has vinegar heart disease." Zhang Yunshan put his finger in a small hole in the tree where it seemed to grow worms, and tasted the taste of his fingers, which tasted like a faint vinegar. After that, the old man held the worm inside the small hook hook, and after many times, it hooked out, and hooked out a large white worm like a bat. Then he applied medicine to the wound of this tree and said to Zhang Yunshan admonishingly: "Lord, if this tree has fruit, then you must pick it when you return the green skin, and after eighty-nine times out of ten, then the tree can survive." Zhang Yunshan then did what the old man said, and the next year the tree grew more and more luxuriantly.
Zhang Yunshan sighed that there is really such a master in this world, even the disease of the tree can be seen and cured, it seems that he has learned less. Since then, he has gained more momentum in his studies, and eventually he has been promoted to erpin as a political envoy.
