Hi there, I am a Chinese teacher.
If you wanna learn Chinese, Pin yin is a must  lesson for every beginer. Pin yin helps you to pronounce Chinese correctly and make Chinese people understand you.
Some of the Pin yin are quite easy for English speakers,like b, p,m.....they sound the same as thoes in English.

However,there are also some tricky ones...like z,c,s,zh,ch,sh....and of course, r....

How to pronounce every Pin Yin in the right way?

Study with me....Learning Chinese is  a fun.....
