In the Japanese period, a small shrine here honored a water goddess. After the war, the story took a more romantic turn. In 1980, the Nantou County government built a temple on the island dedicated to Yue Lao, the old man under the moon who is said to tie couples together. It is remembered as the first temple in Taiwan devoted mainly to him, inspired by a similar shrine beside West Lake in Hangzhou. Group weddings on the water and television filming made it famous. Then, in 1999, the great 921 earthquake destroyed the temple. It also damaged the lake's dam, so the water level dropped and more of the island appeared. A Thao archaeological site was found on it. During planning for the rebuild, the Thao pressed to have their ancestral ground restored. At the end of 2000 the statues were moved to Longfeng Temple, and the island became an indigenous area closed to outsiders. The island then faced another danger. Earthquake damage and years of wave erosion shrank it until, at full water level in 2006, only about 20 ping was left, a traditional Taiwanese unit that works out to roughly 66 square meters. Work began to raise it. When it finished in February 2008, the island was eight times larger, at 160 ping, or roughly 530 square meters. Its height was raised to 751.5 meters above sea level, and a retaining wall at its base now helps slow the erosion.
