The four years it has taken the Chinese artist Zheng Chunhui to sculpt this has been well spent. It's a superb continuous work of art, all on a 40 foot log. It is based on the Chinese painting 'Along The River During The Qingming Festival', which itself was created about 1,000 years ago (see below). Anyone who dedicates themselves to producing such an undertaking is obviously a madman, but l'm glad there are people out there prepared to take on the task.
