The difference between words makes this couplet a household name. Whose light does it touch?

Qi Baishi

Deng, a calligrapher in Qing Dynasty, wrote a couplet: "The sea is the world of dragons, and the sky is the hometown of cranes".

This sentence was not a famous sentence at first, but it was wrongly written by Qi Baishi, a master of Chinese painting, as "the sea is the world of dragons and the cloud is the hometown of cranes". The difference between "heaven" and "cloud" made it a household name and became a favorite sentence written by calligraphers.

Does the old man Baishi really have the ability to "turn stone into gold"?
