During an inspection tour of Wuhan, Central China's Hubei Province on Tuesday, President Xi Jinping once again stressed keeping the lifeline of science and technology firmly in China's own hands and making the country's development more independent, self-reliant and secure.

Over the past decade, China has seen structural improvements in science and technology development and achieved remarkable progress.

China rose from 34th on the Global Innovation Index 10 years ago to 12th in 2021. Spending on science and technology reached nearly 2.8 trillion yuan ($421 billion) in 2021, a 12 percent increase from 10 years ago.

Talented people in the science and tech field have doubled from a decade ago, standing at 5.6 million in 2021.

On June 15, a ship carrying a Chinese "mole" left Tianjin for Lisbon, Portugal.

Designed and made in China, the tunnel boring machine (TBM) can excavate through a variety of soil and rock strata with a circular cross-section.

The western European country bought the tunnel for a drainage project in Lisbon.

It took less than two decades for China to become the world's largest TBM manufacturer and supplier from a country totally dependent on imported TBMs.

How does a TBM work and how is it made?

Let's join Yegor Shyshov around the world's biggest TBM production base.

The 67-hectare base in the Second Industrial Park of the China Railway Construction Heavy Industry Corporation in Changsha, Central China's Hunan Province, has 24 production lines.
