Welcome to Tiangong Temple in Hsinchu, known in Chinese as Tiangongtan. It is a temple of the Jade Emperor, the highest figure of heaven in Taiwanese folk religion. A word of honesty before we begin: the detailed record of this particular temple is thin, especially about its interior. So I will tell you what is firmly known about the temple itself, and I will mark clearly where I am describing the downtown around it. Here is how to picture the setting. The temple stands on the edge of downtown Hsinchu, on the banks of the Keya River, just off Zhongshan Road. Hsinchu's center is packed with famous temples, and Tiangong Temple is the one that looms over downtown with an imposing presence, a worthy companion to the better-known City God Temple. If you have been traveling around Taiwan for a while, you may be feeling a little temple fatigue, because nearly every city and village here has its own historic and sacred halls. Stay with me. This one has a story of rebuilding, of rain, and of one very important street.
