Why is Sky Blue?

He found that when he filled the tube with smoke, the lamp would appear blue on one side and red on the other.

The Chinese nation originated from the Yellow River, but why is the Yangtze River more important to us?
Originally, under the situation that the production technology had not yet been reformed and the population was concentrated in the Yellow River Basin, China’s political and economic center of gravity was in northern China, especially after the Zheng Guoqu was built by the Qin State.

This is revealing the trend of the economic center of gravity shifting south.
