三头六臂

lí kāi qún zhòng nǐ yǒu sān tóu liù bì yě bù dǐng yòng

离开群众，你有三头六臂也不顶用。

You can get nowhere if you stay aloft of the people, even if you have three heads and six arms.

jí shǐ wǒ yǒu sān tóu liù bì zhè ge wèn tí wǒ yě méi bàn fǎ jiě jué

即使我有三头六臂，这个问题我也没办法解决。

Even if I got superman powers, such a problem is beyond me.
