Ancient trees are the precious wealth left by Nature and ancestors, as well as the emotional carrier for people to place their nostalgia on. Guangdong has more than 80,000 ancient and famous trees and 826 ancient tree clusters now. In a group of ancient trees in Zengcheng, Guangzhou, there are no more than 70 trees over 100 years old. Now these ancient trees not only have an "ID", but also professional "doctors" to escort them continuously. Protect ancient trees and maintain nostalgia!
