Every day, there are quite a lot of ferry crossings from the Qiongzhou Strait to mainland China and Hainan Island. In addition to tourists and vehicles, there are other goods here, including some dangerous goods, which will also pass by the ferry. And it is the same boat as ordinary tourists. Dangerous goods have their own parking lot and parking area, so there will be relatively good partitions, and everyone will have a more safe trip. Now as long as they are in and out, their body temperature will be measured.
