Guides receive etiquette training at Slender West Lake in Yangzhou City, East China’s Jiangsu Province, Sept. 29, 2017, as authorities prepare for a tourist peak during the National Daily holiday. Training includes how to best smile or gesture well. Guides are taught to keep a chopstick in their mouth and another on the head to make the ‘best smile.’ (Photo: China News Service/Meng Delong)
