When communicating in Chinese you may often make mistakes using Chinese grammar like:

False:

    去公园在怎么地方换1路公交车？

    Qù ɡōnɡyuán zài zěnme dìfɑnɡ huàn 1 lù ɡōnɡjiāochē

True:

    去公园在什么地方换1路公交车？

    Qù ɡōnɡyuán zài shénme dìfɑnɡ huàn 1 lù ɡōnɡjiāochē?

 

“怎么”用来询问方式、状况、原因等。原句是问换车的地方，应当删去“怎么”，改用“什么”。

怎么 is a word for asking manner, state, reason,etc. The sentence is a question of where to change a bus. Erase 怎么 and use 什么.
