I think you should listening more.... because for the most people which has Chinees as second language is this the most difficult part of learning (speaking) this languague.... you can't do anything but practice/listening!

Punjabi is a very loud and outspoken language..there is nothing hidden about it..sort of hard to explain but its just like the music (Punjabi music) it represents i guess..

hahahah I don't know why I'm not chinese guy but Don't worry ,In Italki there are many chinese and asian people that can yo help you ahahahaha lol!
