Every character on Jiǎoluò Shūwū read as shan in any tone — 2 readings total across the four tones. Pick the tone you mean.
If you have the sound shan but not the character, here are the 2 characters read this way: 山 (shān, mountain, hill, sacred peak), 善 (shàn, goodness; virtue; skilled). They split across 2 tones, so the tone is what separates them.
