Nanjing county is home to more than 15,000 tulou, making it a must-visit for travelers in Fujian. Statistics show that Nanjing's tulou scenic area received more than 3.7 million visitors in 2023, generating tourism revenue of 2.6 billion yuan ($358 million).

In addition to sightseeing, visitors can also experience intangible cultural heritage performances in Nanjing such as puppet shows inside tulou, offering deeper insights into the local culture.

Reflecting on his visit to Nanjing, Jeremy Grinan said: "Tulou was super nice. The people I met there were super welcoming."

"During our visit, it was raining, adding to the sense of calm and serenity. You could see the clouds hanging between the mountains and enjoy local tea while listening to the rain falling on the wooden walls," Grinan added. "It felt like stepping into an old kung fu movie."

The Nanjing county government has considered heritage preservation and tourism development equally important. Many structures of the earthen buildings, due to their age, face issues such as wall erosion and surface damage. Official data shows that Nanjing has invested 8 million yuan in recent years in the restoration of tulou buildings, including repairing roof leaks and cleaning drainage systems.
