Pea tips produced in southwest China's Guizhou Province have become the best-selling products in Hong Kong Special Administrative Region, which have been kept fresh due to cold-chain storage and convenient transportation.

In the early spring, more than 2,000 hectares of pea leaves in Longli County of Qiannan Buyi and Miao Autonomous Prefecture in Guizhou embraced the peak harvest season.

Luo Ying, the owner of a family farm in Wantanhe Town, usually began to pick high-quality pea tips at 8:00 in the morning.

More than 400 farmers living in the nearby areas are working in Luo's farm which covers over 13 hectares. And the tender leaves in the best picking period can be reaped before 9:00, thanks to the high efficiency of diligent workers.

A cold-chain cool store was specially built near the field to cool down the fresh pea tips after the completion of sorting and packaging, and the fresh-keeping facilities help retain the freshness of pea tips to the greatest extent.

Pea tips can be loaded onto the airplane traveling to Hong Kong via a green channel opened for agricultural products after being transported to an airport in Guiyang after a journey lasting for about one and a half hours. And it only takes less than five hours for Luo to complete an order from picking to enplaning fresh pea tips.

"I didn't expect it to be so fast and it took several days to transport vegetables before. Now the transportation is fast. Pea tips can be sold for 360 yuan per kilogram when the market is good," said Luo.

Local authorities in Guizhou Province have ramped up efforts to develop 12 industries with distinctive local features, strengthen the construction of infrastructure such as water conservancy and cold-chain storage facilities in farmland, and improve the quality of scientific and technological planting, driving the sales of pea tips produced in Longli and further consolidating the achievements of poverty eradication.

The province now is pooling its strength to build a regional public brand of distinctive products, and stepping up efforts to construct the logistics and storage facilities in an logistics cluster 15 kilometers away from Guiyang Longdongbao International Airport, allowing local products to be shipped to all parts of the country within as short as 30 minutes.
