Li Hairong, a deputy to China's top legislature, the National People's Congress (NPC), said she wrote a letter to head of the CAAC, saying that during her two recent air trips, she found air hostesses suffering from cold for being thinly clad.

    "Air attendants should put on winter suits in the winter," said Li, former vice chairwoman of the All-China Women's Federation, a mass organization that represents and protects women's rights and interests.

    "Trousers will not affect the images of hostesses nor passengers' attitude toward them. To win in competition, airlines should focus on service rather than the clothes of crew members," Li said.

    In response to Li's letter, CAAC Director Yang Yuanyuan said "the administration attaches great importance to the rights and interests of air staff, and we will discuss with airline companies on the winter clothes of crew members."

    The NPC is holding its annual full session in Beijing, bringing together nearly lawmakers from all over the country.
