In September 2024, TianLu Specialty Coffee Labo and Roastery hosted an exhibition in Xiamen, China, inviting the public to purchase solar lights for Oyanasi Ancient Village and write their well-wishes for the recipients. Nestled among towering mountains with the Longda River flowing through, the village is renowned for its unique ancient architecture. 

Each of the 261 households, built along the mountain using wood and stone, received a solar light. A photo was taken of each recipient and sent to the giver in return. With minimal electric lighting and very small windows to preserve warmth, homes were often dimly lit. The new solar lights now brighten these spaces, offering a striking change. The lights also give children proper lighting for studying, making it easier to enjoy reading and fostering a love for learning.
