Zhaozhou Bridge

Zhaozhou Bridge is deeply engraved in my memory. When we were in primary school, there was a lesson in the textbook about Zhaozhou Bridge. There is also a folk song, who built the Zhaozhou Bridge, who left the jade railings, who rode a donkey on the bridge, who pushed a cart and caused it to slip? The song says that the bridge was built by Lu Ban, and the Eight Immortals came to cross the bridge, carrying the sun, the moon and the five famous mountains to test the bridge, but the bridge did not Some of them were crushed, leaving only a groove made by the wheelbarrow, and the garden pit was made by the immortal's knees when pushing the wheelbarrow. This shows how strong the load-bearing capacity of Zhaozhou Bridge is! It is said that in modern times, heavy machinery weighing more than 600 tons has passed across the bridge! Now, it no longer needs to bear any weight, it only needs to bear the weight of tourists walking over it! The ticket price is 40 yuan. The park is still under construction. It is said that the total investment is 1.2 billion yuan. I wonder how many years the completed Zhaozhou Bridge Park can be preserved? There is free parking at the ticket office, and you can also park on the roadside, but there is no need to park in the open space next to the park, as there is a charge of 10 yuan per time. There are also two exhibition halls, and the package ticket is 50 yuan per person. Zhao County produces pears. As far as I know, there are no prosperous ancient buildings or villages within a radius of 20 to 30 kilometers with Zhaozhou Bridge as the center. Why did the Zhaozhou Bridge, with its extremely advanced ancient bridge-building technology, appear on a not-so-large river in Zhao County that does not need to bear huge weight? Is this really a battle between gods?
