Inscription: April 1940, Darjeeling, Beihong.
Seal: “Xu Beihong” (Square seal with incised characters)
There are two versions of The Foolish Old Man Moves a Mountain. The ink version was made first, then a large-scale oil painting was made later that year. Xu Beihong always wanted to present the piece as a large mural, but this wish was never realized.
