Zhang, also chairwoman of the China Disabled Persons' Federation, urged all Chinese Paralympic athletes to stand firm against doping and compete in sports cleanly, at a press conference.

"Our disabled athletes should behave as real heroes with an unbending will to overcome difficulties. Their faith in winning glory for the country and people should never be tainted by doping," Zhang added.
