紅藤杖(杖出南蠻)
紅藤杖(杖出南蠻) Red walking-stick or cane made from a rattan stem Stick out (originally) a sarcastic remark by Mencius about Xu Xin, a southerner-- those who speak a different tongue than one's own

詩人: 白居易 Bai Juyi
  南詔紅藤杖,西江白首人。時時攜步月,處處把尋春。
  勁健孤莖直,疏圓六節勻。火山生處遠,瀘水洗來新。
  粗細纔盈手,高低僅過身。天邊望鄉客,何日拄歸秦。
