Huang Zijiao, a famous TV host, started a charity event for kids. He invited a lot of celebrities in the entertainment business from Japan & Taiwan to help out with this event. The stars would sign and decorate a bag.
He first mentioned the idea of this event to Jolin and Jolin immediately agreed and started to draw on the bag (see pic above).

The event will be held in Taipei on March 24th.

Thanks a lot to pommy@alan international for translating ^^
