Gong-Bao-Di is the century-old official residence of the Wufeng Lin Family and the only preserved Qing Dynasty official mansion in Taiwan. Built in 1858 by Lin Wen-cha, the fifth-generation ancestor of the Lin family, it was later expanded by his son Lin Chao-dong to its current scale. Lin Wen-cha played a significant role in helping the Qing court suppress the Taiping Rebellion, and after his death, he was posthumously awarded the title of “Junior Guardian of the Crown Prince,” with his residence named “Gong-Bao-Di.” The door gods’ paintings on the main gate have remained clear for over a century, serving not only as works of art but also as symbols of protection. The second main hall, the “Sedan Chair Hall,” served as a reception area where important guests would be carried in by sedan chair, with wall paintings symbolizing blessings and prosperous descendants; these paintings survived the 1999 921 Earthquake intact. The third hall functioned as both a living room and ancestral shrine, with lanterns symbolizing the birth of male heirs. The entrance features “Son-in-Law Windows,” allowing Lin family daughters to discreetly view their future husbands, and an outdoor pavilion provides shade and ventilation, decorated with wooden bats symbolizing good fortune. The fourth hall was destroyed in the 1935 Hsinchu-Taichung Earthquake, leaving only the red brick foundation. The fifth hall was the women’s living quarters, with intricately patterned windows and a partition wall in accordance with strict social customs. The Grand Flower Hall, built by Lin Chao-dong for military meetings and banquets, houses Taiwan’s only Fuzhou-style wooden theater stage, adorned with peony carvings symbolizing wealth and prosperity, with water tanks beneath to enhance acoustics. The central seating faced the stage for the host and guests, while side galleries were gender-segregated, with curtains covering the women’s section to follow traditional etiquette. Today, the Grand Flower Hall serves not only as a historical building but also as a venue for cultural events, exhibitions, and traditional performances, allowing visitors to experience Taiwan’s history and culture. The history of the Wufeng Lin Family reflects Taiwan’s history, with Gong-Bao-Di and the Grand Flower Hall witnessing the passage of time and preserving invaluable cultural heritage.
