•以便 only heads the second clause for positive aims; never place it at the sentence opening or in casual speech.

⚠️ Common Mistakes:

•Using 以便 in casual conversation: replace with 为了 or 好让.

•Placing 以便 at the beginning of the whole sentence: incorrect, it must head the second clause.

•Confusing 以便 with 以免: 以便 means "in order to", while 以免 means "lest / so as to avoid".
