miss A's Jia has apologised for a video she had posted on Instagram.
A few days ago, she posted a video on instagram that showed her riding on an airport trolley.
Although it seemed innocent at the time, the video invoked a flurry of comments claiming she was doing something dangerous.
She has now used her Twitter to apologize for the video, writing, "I didn't know the video of me riding a cart at the airport two days ago would be problematic! I'm sorry!!!
"I won't do something like that again. I'll be more careful!"
