The fare at Xuzhou South Railway Station is 52 yuan. How long does it take to get to Huai'an?

In normal times, it takes more than four hours to get from Xuzhou South to Huai'an with a fare of 52 yuan. Because it is not a direct train of 68 yuan, the direct train will take another 3 hours. There will be constant stops in the middle to pick up people. However, During the National Day, the seats should be filled up at once, so it may be faster, but it is still difficult to get up quickly without taking the expressway.
