《资治通鉴·魏纪·魏纪八》
所以我们不如先保国治民，谨守住自己的国土，至于建功立业扩大疆土，那就要等待有才能的人去干了。我们不要寄希望于侥幸，把成败系于一举，如果不能如愿以偿，后悔就来不及了。 
不如且保国治民，谨守社稷，如其功业，以俟能者，无为希冀徼幸，决成败于一举；若不如志，悔之无及。 
Thus, we are better off securing the nation and governing the people, and firmly protecting our own territory. As for establishing meritorious deeds, achieving accomplishments, and expanding the borders, we will have to wait for someone more capable to do so. We should not bet on luck and rely on one decisive battle. If we do not get our wish, it will be too late for regrets.
