よちよち・習わし

100 days: it's been more than 100 days since the baby panda's birth at Ueno Zoo. She's healthy and has started taking her first tottering steps. In China, it's customary to name pandas after 100 days — though this panda's name hadn't been decided yet at the time of writing. (Note: this post was written on September 24th; the panda was named Shan Shan on September 25th.)
