A coffee bean consists of two symmetric oval parts, which Huang thinks symbolizes the relationship between the Chinese mainland and Taiwan.

"The customs and language here are almost the same as my hometown in Taiwan, which is why I love this place," Huang said.

For Huang, investing here is not only a business decision, but also to enhance agricultural cooperation between his two hometowns and help local farmers in Nankeng.

The park has provided 45 jobs for local farmers so far.

In March, a document outlining 22 measures on agriculture and forestry was released by the central government to enhance mutual exchanges. Huang sees it as a great opportunity for business owners in Taiwan to invest in the mainland.

The coffee park is expected to produce 3 tons of coffee beans annually.

"The indoor cafe here is open to the public every day. I still remember the Spring Festival holiday in 2010, when we sold 4,000 cups of coffee in a day," he said. "The coffee industry might not be familiar to local farmers yet, but I believe the future is bright."

Huang is planning to expand the scale of his coffee planting by 10 times in the next few years, and is developing a butterfly valley to attract more visitors.

"A majority of our customers come because they are attracted by the tulou. In the future, I hope more of them will come for our coffee park. This is my dream."
