proof of denied tourist china visa application

i have been to china last oct. 2011 for two days using tourist visa then i did try apply again this january but then the agency told me that i was denied.the agency told me that they submitted my application in laoag ilocos. but how am i supposed to know that i was really denied? im doubting if the agency did really process my aplication because they just told me im denied without anything to see if im really is..thanks again
