Unscrupulous, unscrupulous.
The so-called "good life is not long, bad life is a thousand years" is actually wrong. Those who can withstand the tide of time will neither be naive enough to think how beautiful the world is, nor will they go to extremes, but this is exactly in line with Sun Tzu's "positive peace and surprise victory" in the art of war. Is the most objective law of the golden mean.
