However, Rome was not built in a day.
不过，罗马城也不是一日建成的。
Your should understand that Rome was not built in a day.
你要知道伟业非一日之功。
Rome was not built in a day, nor in a year.
罗马非一日建成，也不是一年建成。
Rome was not built in a day, what do you think?
罗马不是一日建成的，你的看法？
However, just as Rome was not built in a day, no one can achieve anything without effort.
然而，正如罗马不是一天建成的，没有人能不劳而获。
