Zhu Lin Lin escorts the students home. Our reporter Zhou Huan took pictures in the evening in the deep mountains, with a cool breeze. On the bumpy path, the middle-aged man dragged the boy down the mountain slowly, telling the boy about the outside world while walking... This was the scene after the school of Longxi Primary School in Xianxia Township, Yudu County, Jiangxi Province, more than 20 years ago. More than 20 years ago, Longxi Primary School was a "Cloud Primary School" built on a cliff over 800 meters above sea level. It took more than an hour to go to and from school. After school every day, escorting students home down the mountain has become the daily routine of Fang Lizhang, a Chinese teacher. Mr. Fang's escort every day and every year has set a spiritual benchmark for Zhu Linlin, the student. "Being him" is like a seed that accidentally falls on Zhu Linlin's heart, taking root and sprouting. In 2011, Zhu Linlin went to university, chose to study as a teacher's major, and returned to Longxi Primary School after graduation. At that time, Mr. Fang's hair was grey. Two years later, Mr. Fang retired and said goodbye to his beloved education. "Children are the hope of the village, and our responsibility is to protect the children's growth and teach them well." Before retirement, a sentence from Fang Li Chang was branded in Zhu Linlin's heart. "To return to the mountains to teach is to let more children have a chance to see the outside world," Zhu said. With the relay protection, more and more graduates came back to donate money and materials to build Longxi Primary School. Zhu Linlin said that the original Longxi Primary School was in a tough condition, with only two dilapidated brick and tile bungalows. It was raining hard outside and light rain inside. The teachers at the foot of the mountain were unwilling to come. Now, "Yunduan Primary School" is connected with "local atmosphere". The cement road leads directly to the school gate; In winter, the hot water supply is uninterrupted; The school has built dormitories, and children from far away no longer have to travel to and from school in the morning and evening; The Internet allows children to learn more knowledge... Children's songs resound around the green mountains and relay protection to the flowers. Overlooking by the railing, the mountains in the distance and the children behind them form a moving picture. Zhu Lin said that this is his "big world". (Reporter Zhou Huan) (Liaoxin News Agency)
