Since Beijing raised its parking fees on April 1, parking attendant Yin Liang's life has become even harder.

The 53-year-old, who has been working in Beijing for six years, moved from Zhangjiakou in North China's Hebei province to Beijing, with his 12-year-old son.

"As a single father, bringing up my son is very important to me, but now it's become more difficult for me to play bread winner."
