After entering the Lanyang Plains through Beiguan, visitors will reach Toucheng Town, the town known as the “First City Upon Entry of Lanyang”. Touchen faces east towards the Pacific and is backed by mountain from the north and east. It has a coastline that stretches for 28km, which also presents in varying ways. This long coastline served an important role since the Qing Dynasty, as an important business town. The present Heping Street is the best proof of this.
