The high school graduate said when he first began working as a railway technician, he could barely read a blueprint.

"The Party organization in my company provided all kinds of help for me," he said.

"Just by way of example, they arranged two college graduates to work as assistants with me and provided tools and equipment for my experiments, and when I was too busy to go home during holidays, our Party organization paid the transportation expenses for my family to visit me."

Based on the notes he has kept for years, the farmer-turned-worker has published two books on overhead contact system experiments and methods, which became popular reference books for thousands of technicians.

"All the progress and achievements I accomplished would not be possible without the help of our Party organization," Ju told reporters.

Ju joined the Party in 2008, and he was elected to be a delegate to the Party congress earlier this year.

"Now I feel the responsibility of bringing my fellow workers' and migrant workers' hopes and concerns to the congress," he said.

Feng Tongqing, a labor professor at the China Institute of Industrial Relations in Beijing, said he welcomed the Party's move to include more migrant workers' representatives at the congress, as this will give the group more say.

"It is definitely a good start, but I think what's more important is to set up a mechanism for these delegates to regularly communicate with the people they represent and to listen to migrant workers' concerns and problems," he said.
