China's personal income tax has become a hot topic of discussion in recent years, as despite people's rising wages, inflation means people have less purchasing power.

Although, the threshold was raised to 3,500 yuan ($555.5) from 2,000 yuan last year, the higher threshold has not benefited everyone, especially those who work in smaller cities.

Even white-collar workers earning around 7,000 yuan a month in big cities like Beijing and Shanghai, where people pay large sums of money on accommodation, are complaining about the high cost of living.
