China's ancient cases of "waterwheel" and "vehicle management" were all imported from Central Asia?
No, they were all created by the ancient working people in China.

Water wheel is a kind of running machine developed by working people in ancient China. According to the literature, the waterwheel appeared in the Eastern Han Dynasty. As an important part of China's farming culture, the waterwheel embodies the creativity of the Chinese nation, witnesses the agricultural civilization of China and provides a witness for the history of water conservancy research. The invention of the waterwheel laid the foundation for people to live and work in peace and contentment and social harmony and stability.

The pipe truck, also known as the "water-to-pipe truck", appeared as early as the Spring and Autumn Period. Zhuang Zhou's "Nanhua Jing" recorded that the old man holding Weng in Hanyin was ashamed to use the orange cup, which was a water lifter standing by the well. With the development of society, more and more attention has been paid to the use of water lifting tools, and buckets, buckets, dragon bone vehicles (also known as rollover) and tube vehicles have appeared one after another.

A bucket is tied to both sides of the bucket or basket with thick rope, and two people hold a rope to lead the river to the ground. The bucket is made of thick bamboo poles that pass through bamboo seams and are connected with each other. Supported by wood and stone, it crossed the canyon and introduced water into the field.

A series of hinged wooden boards are put into the sink by the keel car, and the horizontal axis is trampled or rotated by cattle, and the river water in the gully is led to the ground with wooden boards. This kind of truck uses the principle of hydraulic operation to get water from bamboo tubes, and running water can be pumped into the fields by itself without manpower.

Extended data:

In the context of China, "Central Asia" refers to the five Central Asian countries that became independent between Russia and China after the disintegration of the Soviet Union. This geographical concept was first put forward by German geographer alexander von humboldt in 1843, which refers to the Central Asian region where Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan and Afghanistan are located.

The former Soviet Union officially called Afghanistan "five Central Asian countries". China officials also adopted the official definition of the former Soviet Union, so in China, "Central Asia" is equal to "five Central Asian countries".

The "five Central Asian countries" are the products left over from the disintegration of the Soviet Union, and now they are highly dependent on Russia economically. In the wave of the disintegration of the Soviet Union, the three Baltic countries took the lead in declaring independence, and Russia, Ukraine and Belarus further actively promoted the independence of all countries.

At that time, five Central Asian countries opposed the disintegration of the Soviet Union. However, Russia's own economic recession, trying to get rid of the burden and turn the five Central Asian countries into subordinate countries, not only reduces the pressure, but also facilitates control, and finally forms the five major Stan countries in Central Asia.
