2065438+June 2007, mobike completed a new round of financing of 600 million US dollars; At the beginning of July, ofo also announced the completion of a new round of financing of 700 million US dollars. In just two years, colorful bicycle sharing quickly occupied the streets of China. At present, there are more than 5 million vehicles in operation in mobike, with a maximum daily order of more than 25 million vehicles and more than 654.38 billion registered users.

Bicycle manufacturing enterprises, once a marginalized traditional industry, have become a sunrise industry with the arrival of bicycle sharing in China. This year, the overseas bicycle sharing capacity of ofo and Phoenix will reach 6.5438+0 million.

After sweeping through China, bicycle sharing appeared in Cambridge, the bicycle capital of Britain. I saw a bicycle sharing clip in the street, which was an orange cloud floating from China.

The Financial Times reported that the rapid development of bicycle sharing in China is an example of China leading the world in innovation. From sharing bicycles and cars to sharing knowledge, skills and services ... The concept of "sharing economy" originated in the United States in the 1970s, and now it has grown rapidly in China, bringing about great changes in lifestyle.

2. High-speed railway

Crossing the north wind area and Lingnan mountains and rivers, the blueprint of "eight verticals and eight horizontals" is slowly unfolding from the single line between important cities. 2 1 In the second decade of the century, China high-speed rail began to dominate the rail transit. High-speed rail has not only become the first choice for many people to travel, but also effectively promoted economic and social development.

From catching up to leading, from China manufacturing to China standard, China high-speed railway has gone through an efficient and brilliant road of introducing, digesting, absorbing and innovating.

3. Hybrid rice.

The hybrid rice developed by Academician Yuan Longping was proposed by scholars as the fifth invention in China. In fact, this statement is not unreasonable. China is densely populated, and 7% of the cultivated land needs to support 22% of the population. Successful development of hybrid rice can feed at least 70 million people. Food security is not only related to people's daily life, but also of strategic significance to a populous country. Up to now, the cumulative planting area of hybrid rice has exceeded 4.5 billion mu, and the rice yield has increased by more than 400 million tons.

4. A new model of black hole ejecting matter at high speed.

Nature, the top international scientific journal, published an important scientific discovery by scientists in China on125 October (early morning of 26th Beijing time). Liu Jifeng, a professor at the School of Astronomy and Space Sciences of the University of Chinese Academy of Sciences and a researcher at the National Astronomical Observatory, led the team to discover relativistic high-speed jets from ultra-soft X-ray sources for the first time in the world.

This discovery breaks the traditional cognition of astronomy, reveals a new way of black hole accretion and jet formation, and opens a new window for astronomers to understand black hole accretion and jet formation.

5. Hybrid millet.

At present, China's agricultural water mainly comes from deep groundwater. Groundwater will be used up one day, and it is obviously not a long-term solution to rely on groundwater for agricultural irrigation for a long time. Hybrid millet in Zhao Zhihai can change the current situation that agriculture relies on over-pumping groundwater, because hybrid millet uses much less water than hybrid rice. Now, Zhao Zhihai's "Zhangzagu" series varieties have been widely promoted in most northern provinces.
