An annual harvest festival is being held in the Chen Family Village in Zhaoyuan City, east China's Shandong Province. This was a poor village 40 years ago, but now it has developed into an agricultural park with ecotourism appeal. Villagers here earn about 28,000 yuan (nearly $4,000) per year, as much as 60 percent higher than the national average. During the festival, many special local agricultural products are displayed. Local villagers are showing us their new models of agriculture development. Let's check it out.
