February 22nd. I posted a message on Dossa with a desperate heart after my bicycle was stolen within two hours at Songdo Triple Street.
Thanks to the tips from Dossa members, I was able to find two complete bike listings on Bikecell and one wheelset listing on Bungaejangter. On the evening of the 25th, at 8 o'clock, I was able to get my bicycle back through direct trading induced by police officers.
Thank you so much to everyone who gave me tips
