Dinosaur tracks have been found in northeast China’s Jilin Province, according to an announcement by scientists from China, the Republic of Korea and the United States.

Dinosaur tracks have been found in northeast China’s Jilin Province, according to an announcement by scientists from China, the Republic of Korea and the United States.

The tracks were found on a rural mountain road in Longjing City in the Korean Autonomous Prefecture of Yanbian, Jilin in August 2015.

“The tracks include footprints of hadrosaurs that are 55 centimeters long. The trackmaker’s body could have reached 7 meters long,” Xing Lida, associate professor from China University of Geosciences, told Xinhua.

Several tracks of carnivorous dinosaurs were also discovered with various footprint sizes ranging from 43 to 21 centimeters, Xing said.

The discovery will help with research to understand the region’s landscape during the Cretaceous period, Xing added.

Premier Li Keqiang and other leaders on Thursday discussed economic upgrading, Belt and Road Initiative, people’s congress system, poverty alleviation, anti-corruption campaign and other topics with national lawmakers.

They joined deputies to the National People’s Congress (NPC) in separate panel discussions at the NPC annual session.

Joining NPC deputies from Shaanxi Province, Premier Li called for developing high-end equipment manufacturing, information industry, modern logistics and rural e-commerce. Tourism and culture should also be boosted to create more jobs.

The provincial government should further streamline administration, delegate power to lower levels, improve services, play well the province’s role as a key junction in implementing the Belt and Road Initiative, and take a lead in the development of China’s western region.

Joining lawmakers from Jiangsu Province, Zhang Dejiang, chairman of the NPC Standing Committee, said people’s congresses at various levels should implement the decisions made by the Communist Party of China (CPC) Central Committee to ensure effective state governance under the Party’s leadership.

He called for innovation in theory and practice of the people’s congress system, which is China’s fundamental political system.

Yu Zhengsheng, chairman of the Chinese People’s Political Consultative Conference National Committee, joined NPC deputies from Guizhou Province in a panel discussion.

Yu urged the province to continue optimizing the environment for developing private businesses, invigorating the private economy, and supporting private businesses’ efforts to speed up transformation and upgrading.

Yu also highlighted targeted poverty alleviation, stressing more effective measures, enhanced implementation of policies and mobilization of all resources to win the battle against poverty.

Wang Qishan, secretary of the CPC Central Commission for Discipline Inspection, joined NPC deputies from Yunnan Province, calling for advancing the anti-corruption campaign, which accords with the aspirations of the Party and the people.

Calling inspections a kind of “political checkup,” Wang said undesirable working styles including formalism and bureaucratism during the implementation of CPC Central Committee decisions must be rooted out.

Senior officials at key positions must guard against perfunctory working style and endeavor in a pragmatic way to live up to the people’s expectations, he said.

Joining lawmakers from Chongqing Municipality, Vice Premier Zhang Gaoli highlighted the city’s role as a strategic pivot in China’s “Go West” strategy and asked the municipal government to actively fit into the Belt and Road Initiative and the Yangtze River Economic Belt.

He also urged Chongqing to push forward the supply-side structural reform, promote innovation-driven development and high-end manufacturing, coordinate rural and urban development, and protect the Three Gorges Reservoir and the Yangtze River.

Li Keqiang, Zhang Dejiang, Yu Zhengsheng, Wang Qishan and Zhang Gaoli are all members of the Standing Committee of the Political Bureau of the CPC Central Committee.

China will build an undersea lab that can contain dozens of people. “China’s manned deep-sea submersible Jiaolong can hold a few people and stay under water for 12 hours. Our future deep-sea lab station can stay under the sea for half a month or even months,” said Yan Kai, an NPC deputy and director of National Key Lab for Deep-Sea Manned Equipment.

Wan Gang, minister of Ministry of Science and Technology of China, said that deep-sea lab station was listed as a key project in China’s Science and Technology Innovations 2030 Project during a national science and technology conference in January.

According to Yan Kai, the difficulty of building a deep-sea lab station is almost the same as building a space station. Yan said that scientists can cultivate and research deep-sea creatures, explore deep-sea mineral, oil and gas resources and research the genes of deep-sea creatures for medical use.

Yan said the deep-sea lab station will use fuel cell or nuclear power because it will stay under the sea for a long time.

The material used for the deep-sea lab station is a major technical problem. “The submarine pressure in 1,000 meters deep sea is 100 times than the pressure of the atmosphere, which means even a tiny nail will bear the pressure of 100 kilograms,” said Yan.

Therefore, special material with light weight and high pressure resistance will be a must if the deep-sea lab station needs to stay under 1,000 meters of water. Moreover, the problems of deep-sea navigation and communication, precise control and manipulation in lab station also need to be accounted for.
