The ages of the trees have been verified by the Department of Forestry at Chinese Culture University. Although the dating method they employed left some margin of error from the actual age, so the figures are only an approximation, at least they provide an era for reference. Each tree is named after a historical figure from the corresponding era in Chinese history.
