The way the Chinese idioms describe certain things with just 4 words combined together is wonderful as the idiom describes the situation beautifully. One of the idioms that I remembered recently and partially due to the change of events in my life is this phrase that describes a person as someone who is condescending.
目中无人 – mù zhōng wú rén
Usage
就因为她是个副校长，在她眼里，她都目中无人。
