When communicating in Chinese you may often make mistakes using Chinese grammar like:

False:

    明天我们出发学校。

    Mínɡtiān wǒmen chūfā xuéxiào

True:

    明天我们从学校出发。

    Mínɡtiān wǒmen cónɡ xuéxiào chūfā.

 

“出发”是不能带宾语的动词，如果要指明“出发”的地点，应当用表示时空关系的介词“从”，组成介宾词组“从学校”，放在“出发”的前边，做状语。

出发 is a verb which does not take the object. To demonstrate the place of departure, one ought to use 从—— a preposition showing a space-time relationship. 从 plus its object 学校 forms a prepositional phrase, preceding 出发 as an adverbial adjunct.
