"In the concrete forest of a metropolis, Liu builds up in his small space an art world that feels warm and magical," Wu says.

Now Liu's world of sculptures has been transplanted to the third floor of Wu's museum in Beijing, where nearly 200 sculptures and traditional Chinese seal-cutting works are on show.

The exhibition marks the 86-year-old artist's fourth one-man show at the museum since 1981. It includes 57 sculptures from the museum's collection, nearly three-fourths of which Liu had donated just before the exhibition's opening on Thursday.
