There is an interesting story about the town of Longteng that is revealing of the superstitious beliefs that local people once held. When the first settlers started to cultivate land in the area, they believed that Liyu Lake, located nearby, was inhabited by a carp spirit which brought hardship to the people. In order to overcome this evil spirit they planted yuteng (a poisonous plant) in the Longteng Mountain area.
At the same time they gave the mountain in the east the name Guandao Mountain (lit. Guan Sword Mountain) hoping that the Sword Mountain would cut the Yuteng Rattan. In this way, they hoped to poison the evil carp spirit. The ploy must have been effective, for people no longer believe that the evil carp spirit harms the people of Longteng.
In the morning of April 24, 1935 a strong earthquake hit central Taiwan. lts epicenter was near Mt. Guandao, and many buildings in the Sanyi district were destroyed. A reminder of this earthquake remains in the ruins of the arched bridge over Long River. It can be seen from the railway line between Sanyi and Houli.
