Long before shopfronts lined the streets, this land belonged to the Pingpu indigenous people. In 1709 a land-clearing group led by Chen Laizhang obtained an official permit to open up the Taipei basin, and Han Chinese settlers gradually followed. When Monga, today's Wanhua, was crowded and busy, Twatutia was still a small farming village. Its residents grew rice and traded cloth and liquor to the Pingpu for deer skins. The turning point came in the 1850s. In 1851 a man named Lin Lantian left Keelung to escape pirate raids and built a shop on the middle street, which is today the first section of Dihua Street. Called Lin Yishun, it is remembered as the first shop in Twatutia. Two years later, in 1853, Monga erupted in a fierce dispute between the Sanyi group and the people from Tongan over the right to use the wharves. The Tongan people were fewer and had arrived later, and they had been squeezed away from the best riverbank. Their leader Lin Youzao saw that Twatutia, right on the Tamsui River, could become a port. He and his fellow townsmen built a street market and traded across the strait, with Xiamen as the main partner. Over time, the rice yard became the commercial heart of Taipei.
