Career success leads to selection

Jiang Yan doesn't stand out from the crowd of tens of thousands of blue collar workers in the northeastern industrial hub of Shenyang - home to major petrochemical, machinery, traffic equipment and tool factories - except for adornments like the pearl stud earrings she wears to work.

Jiang, 44, is the deputy chief engineer at the design institute of Shenyang Blower Works Group Corp in Liaoning province.

She became a delegate of the 19th National Congress of the Communist Party of China due to her achievements and contributions to the design of China's first large-scale ethylene compressor.
