Market vendor Hoang Thi Tich (green headscarf) of Na Kha Village says the market was once purely a trading hub, but since late 2023 young vendors have flocked to sell goods and film content.
On regular days some 10 professional cameras are set up, but on main market days, that number triples or quadruples, with YouTubers sometimes outnumbering buyers.
Initially camera-shy, the 59-year-old is now used to being filmed. Now, whenever she buys something, she even reminds the vendor to start recording, she says.
"I know how hard these young people work on their videos, so I want to help," she says. Since the YouTubers began frequenting the market there have been more visitors, boosting sales, she adds.
