I don't need to correct your entry since others had done a great job.  However these are my comments. 

1.   Never introduce yourself as "lovely", "good", "nice". Sounds so superficial.  Of course you are nice.  Who would want to introduce themselves as a nasty, no good person?

2.  Chinese place names.  There are two styles.  The older style is breaking the name into its basic sounds like, Guang Zhou.  The newer style is to connect them together.  In this case, you do not capitalize the 2nd sound.  Therefore it should be Guangzhou and not GuangZhou.  Try to use the standard conventions, for example, Hong Kong and not Hongkong or even Xianggang.  Shanghai and not Shang Hai.
