The couple's two children have also developed an interest in artifacts. Their son, Zhao Ruyang, 17, is especially interested in history, and shares what he learns in his history classes at school with his father.

Their daughter, 20-year-old Zhao Xueting, is an industrial design major at the Jiaxing Vocational and Technical College in Zhejiang province. Last winter, she returned during her holidays and assisted the archaeological team with her professional drawing and mapping skills.

"I have grown up in this kind of environment, and so I am passionate about archaeology and cultural heritage preservation," Zhao Xueting says.

"If given the opportunity, I am willing to carry forward the legacy of faith started by my father and grandfather."

In recent years, the importance of the Dalt archaeological site has gained wider recognition. The local government is developing an archaeological park and exhibition hall — initiatives that fill Zhao Yong with hope.

He envisions tourism bringing prosperity to the village, countering the challenges of an aging population, and the departure of young residents.

"I want to protect these cultural artifacts, preserve them for future generations, and help more people discover the beauty of my hometown," he says.
