For people like us living in Hong Kong's concrete forest, what we breath is 'dead air', what we see is a white sky, hence, visiting Sichuan & Yunnan in autumn (between October & November) was really a great experience! I was fascinated by the velvia blue sky & snow white clouds, lungs were opened by breathing in the air at an altitude over 3000M, eyes were soothed by seeing an infinite distance...i hope u all enjoy this gallery & visit these places one day!
