As flowers come into bloom in Nanchong, Sichuan province, beekeeper Tan Kunming enters his busiest season.

Tan, a resident of Nanchong's Gaoping district, has 300 beehives, each weighing over 20 kilograms. Amid the vast expanse of flower fields at the foot of Lingyun Mountain, he periodically opens the beehives to monitor honey production progress.

"Where there are flowers, there I shall go," he says. Each year, he chases the blossoms across half of China's vast landscape, covering a distance exceeding 30,000 kilometers. He earns an annual income of around 150,000 yuan ($20,600).

"The hardest part of beekeeping is loading and unloading those heavy hives. All the rest is pure sweetness," Tan said.
