What is \'Throwback Thursday\' (#TBT) on social media?

Hi, [이름] [이름],  
Thank you for your brief explanation of the “Throwback Thursday” (#TBT) social media trend. It is also one of the examples when people share their memories, which as you have already mentioned, makes them one of the most nostalgic and reflective people. After all, such posts evoke in us the most cherished time. It is thanks to social networks that we can share memories with each other more often. Keep up the great work!
