Hu Xiaoyan, one of China's first three migrant workers to sit as a deputy to the National People's Congress (NPC), expects to submit her first motion on protecting migrant workers' rights during the ongoing NPC session.

Nearly 3,000 deputies are attending the annual session of the national legislature, which began on Friday, to consider key issues facing the country.

Being an NPC deputy since 2008, Hu has submitted seven proposals, all concerning the welfare of migrant workers.

"To forge a motion is more difficult than submitting a proposal," she noted.

A motion becomes legally binding when it is adopted, but a proposal is not.

According to the Organic Law of the NPC and NPC rules for the discharging of its duties, a motion can be raised by a provincial-level delegation of deputies to the NPC or a group of at least 30 NPC deputies.

It can also be put forward by the presidium of the NPC, the NPC Standing Committee, special committees of the NPC, the State Council, the Supreme People's Court, or the Supreme People's Procuratorate.

"Before the NPC session, I received many phone calls and emails from migrant workers. Most of them were about the issue of the default of salaries," Hu said. "So this year I decided to hand in a motion about setting up a system to prevent employers from delaying payments for migrant workers."
