Zhou Suitong looks at his road map in Tianjin, Aug 27, 2012. Zhou started to ride from Beijing, where he worked, to Jieyang in South China's Guangdong province to propose to his girlfriend Gui Zi. He plans to finish the journey, lasting about 2400 kilometers, before Sept 14. He said in his micro blog that "I chose this way to propose not to show off but to testify that I will keep my promise to make you happy no matter how hard and difficult life can be." He was carrying a 3D model that says “Marry Me, Gui Zi”.[Photo/Xinhua]
