Purpose of an action (为的是)
Explanation
为的是 (wèideshì) is used to state the PURPOSE of the action just mentioned in the preceding clause, forming a purpose compound sentence (a two-clause sentence in which the second clause states the purpose). It means "in order to", "for the purpose of".
[clause stating the action]，为的是 (wèideshì) + [purpose]. The first clause states what was done, the second clause begins with 为的是 stating the reason/purpose of that action. For example: 我把车停在外面，为的是走的时候方便.
When you want to clearly explain the purpose behind an action already stated, placing the purpose part AFTER. Used in both speech and writing, with an explanatory, affirmative tone.
为的是 (wèideshì) puts the purpose in the second clause and the action in the first clause; different from 为了 (wèile - in order to, for) which usually puts the purpose in the FIRST clause (为了方便，我把车停在外面). The content is the same, only the position and the focus of emphasis differ.
Vietnamese learners are used to 为了, so they often place 为的是 at the beginning of the sentence like 为了. This is wrong. 为的是 must come in the second clause, after the action has been stated: say 我把车停在外面，为的是…, not 为的是方便，我把车停在外面.
