The Hu ZiBei (Tiger Tablet), located at the border of Taipei City and Yilan County on the Caoling Historic Trail, has an elevation of approximately 330 meters. It was erected by Liu Ming-Deng, the Taiwanese general of the Taiwan Prefecture. The site where the tablet stands has strong winds throughout the year, which posed a threat to travelers. Therefore, a "tiger" character was inscribed here, symbolizing the phrase "clouds follow the dragon, wind follows the tiger," to ward off the wind evil. The erection of the tablet to suppress the evil spirits also serves as a reminder to travelers to be cautious when passing through this area due to the strong winds.
The Caoling Historic Trail was gradually constructed by the indigenous Plains Aboriginals to facilitate communication between the two plains on either side of the Snow Mountain range. During the Qing dynasty, there was a Plains Aboriginal tribe called the "Sanjiaozhai" in what is now the Gongliao District of New Taipei City, with a population of over 500 people as of 1917. The tribe initially settled along the coast, particularly near the mouths of streams, and made a living by fishing. Even today, there are still descendants of the Plains Aboriginals living in this area.
