Conservation zones and reef restoration programs have been adopted, and authorities have started monitoring poachers, who face strict fines if caught.

In addition to the transformation of the fishing industry, tourism has played a key role. Once a boat captain, Hong Yongjun is now the owner of an ocean-themed guesthouse. Visitors can enjoy the ocean view and murals made by fishermen's wives, as well as go on fishing trips.

"We've been developing this industry since 2006," said Zhang Zhiyan, head of Tian'ao village.

The "Five Fishing Villages of the East Sea", which includes Tian'ao and four neighboring villages, provide fishing experience, each with a unique style.

About 30 kilometers to the northeast lies Huaniao Island, where the Huaniao Lighthouse has been guiding ships since 1870. The island now offers tours for a limited number of guests centered at the lighthouse. The tour limits visitors to one boat - holding 280 people at most - and includes a two-night stay in guesthouses on the island.

"We're very cautious when it comes to the environmental capacity of the island, plus we don't plan to build any big, fancy hotels," Wang said. "So it's actually difficult to make a booking during the summer."

"This fits our idea of high-end tourism, as we are building China's first high-end micro-resort on an outlying island," said Cao Jiayan, head of the Huaniao Tourism Development Company.
