I had a chance to go to "BORN PINK" concert by my favorite girl group, BLACKPINK three months ago. This tour was celebrated at My Dinh stadium, Hanoi capital on 29th, 30th of July. This concert took place took place in an outdoor stadium. Firstly, I was worried that the concert would be cancelled because of the heavy rain. Luckily, the weather became better, the concert was still on. BLACKPINK performed many famous songs such as: How you like that, Kill This Love, Pink Venom, etc. All the fans chanted and danced together. There were also solo stages of each member of group. I really liked the performance of Rosé because her voice was so beautiful. I was surprised when they covered the "See Tình" dance, we all shouted loudly. We all felt excited when going to this music event because we could make new friends and enjoy the exciting atmosphere
