Big cultural event to open with Zhang Guoyong's baton

After conducting a concert with Buenos Aires Philharmonic Orchestra at the Colon Theater in Buenos Aires earlier this month, Zhang Guoyong went to watch a tango performance.

Although the neighborhood - far from downtown, where he was staying - looked like a regular place, the performance was unusual. Couples in their 80s danced the Argentine tango.

Not professional dancers, their moves caught Zhang's eye.
