《资治通鉴·唐纪·唐纪四十四》
我听说治理有时会生出变乱，变乱有时会有助于治理；有因没有危难而失去成业的，有因诸多磨难而振兴邦国的。
臣闻理或生乱，乱或资理，有以无难而失守，有因多难而兴邦。
I have heard that governance can sometimes lead to chaos, and chaos can sometimes be conducive to governance; there are those who lost their careers due to the absence of danger, and some who revived the country due to setbacks.
