How can i get a tourist visa in china, the first time i applied year ago was denied.

Erma, all I can say is that it’s possible for you to get it as long as you make full preparation and provide all the required documents.
You need to provide those documents including your passport and copy of its data page, the completed application form affixed with a passport-style photo, proof of your financial support, round trip air tickets and hotel reservation, or an invitation letter from your friend in PRC.
