A few days back, B2ST unveiled a special music video for "Mystery", a song from their 2009 album 'B2ST is the Best'. It's just been revealed that the video hit #1 on popular Chinese music site, Yin Yue Tai, for the third week of February!

"Mystery" was a very popular track upon its release, and helped propel B2ST to stardom. The music video that topped the Yin Yue Tai chart was a special edition video made specially for B2ST's "Beautiful Show" world tour. It was publicly released on Valentine's Day due to overwhelming fan requests after its initial unveiling at their Seoul concert.

This #1 ranking is significant for B2ST since it represents strong overseas interest in the group. The boys can now progress confidently towards preparations for their upcoming performances in China.

In related news, B2ST will be performing the Chinese leg of their world tour with the "Beautiful Show in Shanghai" at the Shanghai International Gymnastics Center. The performance, which will be held on February 25th, follows successful concerts in Seoul and Berlin.
