An old pioneer lost his horse-a blessing in disguise is a blessing in disguise. When you are in trouble or even fail, you might as well change your angle, never "bump into the south wall", but be good at facing reality from another angle in time, solving problems, getting rid of difficulties and moving towards success. Referring to the proposed theme:
Viewed from the side, a whole range; Seen from the end, it is a single peak.
Enlightenment from every cloud has a silver lining
Look at the problem from another angle
All roads lead to Rome.
