For over 6,000 years, the temple fair at Taihao Mausoleum in Zhoukou, Henan, has brought people together. What was once a simple "Ni Ni Dog" clay whistle is now recognized as intangible cultural heritage. Dirt paths have given way to clean, wide streets, yet the fair still carries prayers, family wishes, and childhood memories. The temple fair remains the same, while the hometown quietly transforms.
