At the "BTS 10th Anniversary FESTA" at Han River Park in Seoul on Saturday, An estimated 400,000 people wandered among various exhibits including a BTS history wall, stage costumes and commemorative sculptures, many in the band's signature purple colour.

The band is on temporary break as a group with two of its seven members currently doing mandatory military service but the 10th anniversary celebration did not stop.

BTS leader 'RM' read out fan messages, performed and received calls from fellow members 'Jung Kook' and 'V' at the celebration.

"Time goes by so fast. Everything has changed and I've changed a lot. I'm not sure what I'm going to be doing with what feelings on the 15th and 20th anniversaries, but my love for you won't change", 'RM' told fans.

The festivities climaxed with a fireworks show on the Han River, with organisers, local police and fire authorities estimating about 400,000 people in attendance by 9 p.m.

Most of the fans and citizens left after tidying up the place where they stayed. The lawn in the park was filled with many people but it was so clean that there was almost no garbage with the mature fan spirit and civic consciousness.
