Flight attendants from China Southern Airlines showcase uniforms worn since the 1970s on Wednesday at a public display in Guangzhou, capital of South China's Guangdong Province. Uniforms evolved over the past four decades with China's reform and opening-up. China Southern Airlines said in September that it plans to more than double the size of its fleet to 2,000 aircrafts by 2035 and is exploring ways to cooperate with low-cost carriers. Photo: VCG
