Photo taken on July 30, 2020 shows the Kantan No.3 offshore oil platform in the northern waters of the South China Sea. The Kantan No.3 is a semi-submersible oil platform developed domestically by China in 1983. Its 18 well-drilling team members work 12-hour shifts non-stop to detect marine oil and gas resources, which are often found in seabeds 5,000 to 6,000 meters underwater. Life on the oil platform is characterized by toil and boredom, as the weather is scorching hot and there is no mobile phone signal. Typically, the well-drilling workers have to work 28 consecutive days offshore before they can go onshore on a holiday with an equal time length. In over three decades since its started operation, the Kantan No.3 has rigged more than 160 oil and gas wells. (Xinhua/Pu Xiaoxu)
