Wang Huihao from Qionghai — a regular at the Harvest Festival — once again used the event to promote local specialties. This year, he introduced a range of agricultural products, including camellia oil.

More than a decade ago, Wang led the formation of a specialized farmers' cooperative for the cultivation of oil-seed crops. In collaboration with universities and research institutions, the cooperative has evolved into a comprehensive enterprise encompassing seedling cultivation, planting, processing and sales, with an annual output value exceeding 10 million yuan ($1.4 million).

Wang Dezhi, a vendor from Baisha Yacha Supply and Marketing Cooperative, showed off Baisha's fungus ganoderma, five-fingered peaches and smilax. Participating in the festival for the first time, Wang was delighted to find that attendees were not only interested in viewing the products but also eager to purchase them.
