Chapter 58 of "Laozi": "Misfortune is where blessings depend; blessings are where misfortune lies."

The meaning of this sentence is: blessings and Disasters are interdependent and transform each other. Bad things can lead to good results, and good things can lead to bad results. This implies that people should be modest and prudent in good times and guard against arrogance and impetuosity; if they are complacent and arrogant, it will breed disaster and turn from blessing to disaster. In the face of adversity, we must be persevering and diligent, and we can turn adversity into good times, from bitterness to sweetness.

xi: classical Chinese particle, equivalent to "ah" in modern Chinese. Rely: rely on. Fu: hide.
