BEIJING, March 10 -- Vegetable farmers, security guards, construction workers and foot masseurs are among more than 2,900 people reviewing the draft revision of China's Legislation Law at this year's parliamentary session.

Workers and farmers are increasingly seen at the National People's Congress (NPC), China's top legislature, reviewing drafts and voting for the passage of laws alongside government officials and industry tycoons.

The share of workers and farmers elected as deputies to the 12th National People's Congress rose to 13.42 percent, up 5.18 percent from the previous term.

One of the stronger voices representing grassroots delegates is Xue Haiying, a sanitation worker from Tianjin who caught media attention after pushing for increased medical benefits and better living conditions for migrant workers last year.

Part of the reason for Xue's proposal was the plight of a co-worker who was diagnosed with liver cancer last year. The medical costs for the disease left the co-worker's family in huge debt that will likely take years to pay off.

In the city where Xue works, sanitation worker's monthly pay is around 1,680 yuan (268 U.S. dollars). After paying for rent, parental care and children's education, only a pittance is left for health care, Xue said when proposing the increased medical benefits in 2014.

In a response from the China's Ministry of Human Resources and Social Security, officials told Xue addressing her concern takes time.

This year, Xue is continuing to push for a solution of the issue.

Despite a low income, Xue has equal power over proposals at the NPC as Pony Ma, who presides the 160-billion-dollar Chinese internet giant Tencent.

Though they don't have illustrious education or abundant personal wealth, grassroots NPC deputies are a constant source of change and solutions to persisting problems at the lowest level of the Chinese society.

They garner just as much, if not more, media attention as the wealthy and powerful lawmakers, since many challenges the country faces arise from where they work and live.
