Mug with Chinese seals

The first day back to work - officially, if yesterday didn't count.

Bought this mug at Shanghai Pudong Airport as a New Year gift for myself. Different patterns of seals with writing scripts give a perfect sense for me to run a culture talk on calligraphy - but they are too old to be recognised by me.

But now under pressure to get my slides ready for Thursday's presentation at a conference in Cardiff.
