You can catch more flies with honey
Can I omit 'than vinegar' like what I heard of? And if there're some similar expressions, please tell me that.

Question

Answer

A similar idiom in meaning would be "better to use the carrot than the stick"

This refers to the concept of a rabbit doing something you want for a reward (carrot) versus a rabbit doing something you want out of fear of being hit (stick).

Answer

Yes, you can!  The phrase is familiar enough that we can adapt it.

Another well known example of a shortened proverb is "great minds think alike".  Originally, the full sentence adds "...and fools seldom differ", but not many people are aware of that extra phrase.
