Lovers' graffiti causes a storm

Police are 'really angry' over two names scrawled on palace relic

Two lovers who carved their names on a 300-year-old bronze vat at the Palace Museum have sparked a heated debate online and Beijing police suggested on Tuesday that the couple turn themselves in.

The names "Zhang Tao" and "Liu Ya" were scratched into the vat above one of the two handles, with a heart drawn around the names.
