All the longan is transported to China from Thailand. During longan season, from August to May, it costs about 160-180 yuan. This year, longan plantations in Thailand have suffered heavy rains as well as drought, which have negatively affected the yield. The cost of transportation has also increased. Since longan requires additional processing and preparation before it can be sold on the market, the costs have increased significantly. Longan merchants said that every truckload became 2000-3000 yuan more expensive. However, it must be admitted that transportation costs increase every year with the arrival of the Spring Festival.
