Tea farmer Luo Xianhua from Tongmu, a village nestled deep within the Wuyishan National Park, also serves as a forest ranger for at least 15 days every month.

Inscribed on the UNESCO World Heritage List as a mixed cultural and natural heritage site, the national park is home to the world's most well-preserved mid-subtropical forest ecosystem at the same latitude, and plays a critical role in global biodiversity conservation.

While on watch at the Tongmu conservation station inside the park, Luo patrols the forest, monitors wildlife, checks for fire hazards and prevents illegal logging. Uniforms away, Luo tends an alpine tea garden in the park to earn the bread for his family.

"Good environment is a guarantee to quality tea products," said Luo, adding, "12 people from my village have joined the ranger team to help protect the national park."
