Sticky rice bridge
With Lin and the community association’s chairwoman, Do Shojen, we drive to the locally famous Cuigu (“emerald valley”) Bridge.
Lin points downstream: “That’s the water intake for the Liudu Water Treatment Plant right there, so you know that the water here is especially clean.” A glance under the bridge shows that the water is indeed crystal clear. Formosan stripe dace and Taiwan torrent carp, species that are extremely sensitive to water quality, inhabit the creek. Lin and other locals carry out patrols, confronting anyone they deem suspicious. If they discover that someone has released non-native species such as tilapia, they mobilize immediately, working through the night to catch the fish. The entire village is committed to these patrols to protect the native fish.
The Cuigu Bridge looks brand new, but there is in fact an historical attraction underneath it: the remains of an old “glutinous rice bridge.” A stout hexagonal pier stands under the bridge deck. Back in the day this was built by locals from stone blocks held together with a mortar composed of glutinous rice mixed with red lime, brown sugar, and other materials. The construction method may seem primitive, but the pier has survived countless typhoons since 1949.
“The techniques used by our forefathers were outstanding,” says Lin. “Upstream there were piers constructed of concrete that were destroyed by typhoons.” From Fumin Riverside Park, you can see rubble in the creek from those toppled concrete bridges. Yet this pier made using glutinous rice still stands erect after many decades of exposure to torrents and typhoons. It is indeed remarkable that rice has weathered better than concrete.
From the bridge, you can see a famous local landmark: Mt. Shishi (“stone lion”). The year that Lin graduated from Maling Elementary School, his entire class climbed that peak. It was a typical trip for a graduating class of the era. Maling Elementary is more than a century old. In recent years it almost closed because of declining enrollment. Now it has turned into a “forest elementary school”—one much loved by the Taipei parents who send their children there.
Still standing after many decades, this bridge pier was built using mortar made with sticky rice. Its longevity bears witness to the wisdom of earlier generations in understanding how to coexist with nature. The rocks under the bridge feature unusual “giant’s kettle” potholes.
