To find a suitable environment in which to live, Tu traveled throughout Taiwan for two or three years. Up north, he visited places such as Shihting, Nankang, Hsichih, and Chungyi. In some places, the land was too expensive. In other places, the mountains were too steep and there was not enough land to build on.
