I just came back from a classmate reunion at noon of today.  The restruant is located in the back "square" of the headquarter of MRT, on Zhongshan N. Road, Taipei.  That is the first time ever that I have been there.  The open space of the "square", as well as the open space in front of entrance of underground mall, was swarmed with several group of young people doing street dances, most of them were teen girls. 

There were also street dances "performed" in other MRT stations, for example, in Dahu Park station in my neighborhood.  The dance itself is a good exercise which can let go part of the excessive energies from those young people.  However, "performance" in public areas may bring about some problems, mainly because the dancers are not licensed buskers.

I love to see those young girls dance, and I care about other concomitant problems, too.
