还记得一起荡秋千么
[hái jì dé yī qĭ dàng qiū qiān me]
This is reminiscent of a simple but joyful activity - swinging on a swing together. It's used here perhaps referring to some innocent and memorable times, possibly with someone who once had a special relationship or bond with the user. A nostalgic nod to lost moments of shared innocence and fun.
