Musical dynamo Lee-Hom Wang just won't leave his guitar behind.

The singer-songwriter was signed on Wednesday by Bosideng Menswear to be the Chinese brand's new endorser. Yet at the signing event in Beijing, Wang brought his electric guitar on stage and belted out several of his hits, turning the event into a mini concert.

During the intervals, Wang high-fived his fans and interacted with them like he did at his live shows. His band accompanied him.

Wang also invited fans to his actual Beijing concert, scheduled for later this year.
