Cleaner Peng Wencai picks up the garbage on the edge of the cliff in Emei Mountain in Sichuan province, Oct 5, 2014. Peng has been doing the job for 14 years. He said he is glad to see that the garbage in this year's National Day holiday is less than the period over last year and he hopes that the day he will no longer go down the cliff to clean will come soon.
