In Wangjia Village, Huangshan, Rongcheng City, Shandong Province, there is a lush red pine forest, which is particularly eye-catching. Red Pine dikenali sebagai "Pokok Treasure Utara" dan kebanyakannya diedarkan di kawasan Gunung Changbai di timur laut ke Little Xing'anling. Why are red pine that grows in the northeast breeding and forested in Rongcheng City? This has to start with an 81-year-old man in the village - Song Zhonghua.
Over the years, he has donated 4,980 red pine trees free of charge, worth nearly one million yuan. Today, 81-year-old Song Zhonghua is still busy among the red pine forest.
