For ten years now, two neighborhoods in Southern Taiwan have chosen to make light their calling cards. With their colorful, artistic lanterns that line the streets and canals, the Tainan Phoo Tse Lantern Festival and the Yuejin Lantern Festival offer more than just opportunities for Facebook and Instagram photos. For their locales in greater Tainan, the festivals have also made deep cultural impressions and become important sources of living memories.
