A lot of choy sum, a type of cabbage that is common on dinner tables and in Cantonese restaurants in South China, is often not grown in the region. Yuanzhou district of Guyuan in northwest China's Ningxia Hui autonomous region sells 70 percent of its cool-weather vegetables to other areas.
Guyuan’s ‘cool-weather vegetables’ refer to breeds produced in places with cool summer temperatures; this includes cabbages, carrots and onions. With five vegetable firms and more than 70 cooperatives involving 17,000 households of local farmers, Yuanzhou is estimated to reach a total output of 700,000 tons valued at more than 1.8 billion yuan in 2022.
Choy sum is one of the mainstays in Yuanzhou. The first crop is usually planted in March or early April. In less than two months, the vegetable can be served to people in the GBA. Shipping via cold-chain logistics takes less than 36 hours.
