Others hop on tourist boats that set sail along the river, trying to get a closer look at the landscape of the country and its people's livelihood.
Local tourism agencies say winter is the slack season for sightseeing on the Yalu. They have been receiving few tourists lately, with some wondering if this has anything to do with the new round of sanctions slapped on North Korea by the United Nations.
Dandong tourist agent Xi Kun said they have to negotiate with the North Korean government before they can take tourists onto the Yalu River for sightseeing. Tourists can see the houses of North Korean soldiers and ordinary residents, as well as people living across the river, including male and female soldiers on patrol, fishermen and civilians waiting to board ships.
Constantly living under curious gazes, some North Koreans living near the border are not happy with this business. During the short journey on the boat, a tour guide reminds tourists not to take photos of North Korean soldiers when the boat passes near them, otherwise the soldiers may throw stones at the boat.
