Sixty-year old farmer is obliged to sweep the street for 31 years.
Sixty-year old farmer duty for the village to sweep the street for 31 years modestly named gold hard to buy good body diesel generator | diesel generator price / 2012-05-28
In this case, Jing Buchun, a villager in Xi’ai Shu Village, Cheng’an County, Hebei Province, has so far been obliged to sweep the streets of the village for 31 years. Talking about him at the age of 67, the villagers all praised him and said that the old scene is a good person.
In 1981, the warm-hearted Jing Buchun was elected as a trader by the villagers, obliged to contact the traders who bought agricultural products in the village. However, he soon discovered that small business hawkers were unwilling to come to the village to do business. When I asked it, it was because the road conditions in the village were poor and the vehicles could not get in and out. “At that time, the two main roads in the village were full of accumulated water all year round. Not to mention the vehicles. Even if walking, they have to walk along the corners.â€
In order to change this situation, Lao Jing bought several bamboo rafts and shovels. He arrived at the north-south street of the village at 4:30 the next morning, sweeping streets, flatlands, loading cars... When the villagers wake up from their sleep. He came to work home. However, no one in the village thought that the old scene was sweeping, leveling and pushing for 31 years.
Many relatives and friends advised him, “No one pays you, why are you doing this work? Isn’t it stupid?†Lao Jing has his own thoughts: “I come back every time I go back from the street. Khan, he had a hard body and he had a hard body to buy! It would also make those who walked feel at ease!
The villager Jing Jianmin recalled that there was snow once a night last winter. Early the next morning, he got up early and was ready to sweep snow. When he opened the house, he found no traces of snow in front of the door. He first glimpsed and then discovered that the old scenery in the distance was trying hard to put snow on the tricycle. Jing Jianmin suddenly felt hot in the heart. He said nothing and ran to clean the snow on the street with the old scene.
The road gradually became even, and there were also more small business hawkers. The agricultural products harvested in the masses were sold. Old King said that it can bring convenience to everyone and is worth more than anything else.
Nowadays, the street where the old scene is often cleaned has been cemented and installed with street lights. He no longer has to carry the shovel out, but his habit of sweeping the street has not changed. In the past 31 years, how many bad brooms have been used, and even he himself cannot count.
“In the past two years, I have also insisted on sweeping the streets every day.†Wu Meisheng, a villager in the same village, proudly told reporters: “This village is not only old scene but also ours.â€
