干 = 做 啥 = 什么 = 嘛 啥东西 = 嘛东西 = 什么东西

干啥呢/干什么呢 = what are you doing？ 干啥/干什么 = what's up？ If someone call your name in a sudden, you can reply him/her with '干啥'. (the same meaning as '怎么了') It implies the meaning '你叫我干啥？'='what's up？/why do you call me？' but if '干啥/干什么' is not used as a single sentence, it means 'to do something'. for example, 你在干啥？= What are you doing？ 你要我干啥？= What do you want me to do？ 我得干点啥。= I need to do something.

幹啥 Means "what are you doing?". It's the same as 你在幹甚麽 and 你在幹嘛 啥 Is Dongbei dialect for 甚麽, but it now widely used across all of China. You'll often hear people say 這是啥玩意兒？ or 啥玩意兒這是？ in the north. Laurence

Much of the meaning must be inferred from the context. FOR EXAMPLE 干啥？and 干啥！！！are very diffirent .first is ask what shall i do ,second is what you want to do .

“干啥" means "干什么" People from the north of China use "干啥" more than the southerners do.
