In his essay collection Rong Zhai Suibi, Hong Mai (1123-1202) of the Southern Song describes how south of the Yangtze below Nanjing, rhododendrons grow all over the mountains almost as thick as a jungle. Apart from sticking a sprig or two into the ends of their shoulder poles, the woodcutters bundle the branches up for fire-wood.
南宋《容齋隨筆》裡，說南京以下的長江南岸杜鵑彌山亙野，與榛莽相差無幾，樵夫們，插一、二枝在簷頭之外，都是把它捆紮起來，當作柴薪。
