The Office built in 1925 locates in today's Travel Service Center of Confucius Historical Area. When Taiwan was under Japanese Rule， the office was eatablished of the forestry department. There are two tall Monkey Tail Trees outside the office building planted in 1951. The trees are 3-meter apart， and lean to the right together. It looks like that they are holding each other， and the local thus also calls it " Couple Trees."
