Established in 1978, the Wenjindu checkpoint has served as a major gateway for the supply of produce from the Chinese mainland. Fresh vegetables, fruits, frozen meats and livestock passing through this checkpoint account for 80 percent of the daily supply of such produce to Hong Kong. As such, the checkpoint is known to Hong Kong people as "green lifeline". Latest figures show that in 2019, Wenjindu processed a total of 1.36 million metric tons of fresh produce to Hong Kong, valued at HK$2.78 billion ($357.39 million).

China Daily interviewed two vegetable wholesalers, who have been supplying fresh vegetables, such as pak choi, pumpkin, baby cabbage and Chinese cabbage, to Hong Kong for years.

We also interviewed officials at the Shenzhen customs, who are taking measures to ensure the quality of the produce at the source by adopting a quality control system combining professional testing, daily supervision and speed screening. The Wenjindu Customs set up a green channel to ensure quick inspection and quick release.

At the end of the interview, all staff members from Wenjindu wished Hong Kong compatriots a happy new year.
