cooks有厨师的意思，那too many cooks spoil the soup这句话的意思可以翻译成“太多厨师去煮汤”，煮汤这件事，人多不一定行，相反会手忙脚乱。所以意思是指“人多误事”。

【例句】
We should limit the number of people involved in the project， because too many cooks spoil the broth.
我们应该限制参加这项工程的人数，因为人多反碍事。

There were 15 people in our meeting this morning, all from different departments and each with different opinions. We didn’t manage to complete any of the tasks we had planned. Too many cooks spoil the broth!
今早的会议有15个人参加，他们都来自不同的部门，而且意见迥异。我们没有完成任何原本计划达成的目标。真是人多反倒误事！
