I want to go to Hangzhou from Jinan. What kind of transportation is cheaper?

I often take the T 177 express train from Jinan to Hangzhou. The train leaves at 6: 37 pm in Jinan and arrives in Hangzhou around 7: 00 the next morning. I only know that the price of the middle shop is 265 yuan, and it may be raised a little now, and the time may be advanced. This train is the most comfortable train to Hangzhou. There is also a train from Yantai to Jinhua West to Hangzhou via Jinan. It is green. However, it's almost time. Arrive in Jinan at 4: 00 pm, and arrive in hangzhou east railway station at around 9: 00 the next morning. The original fare is about 140 yuan, which is relatively economical. You can sit in this season because it is too hot in summer and there is no air conditioning. Then there is the sleeping car, which has never been taken. The key is insecurity, which takes about 12 hours. Then there is the plane, which is more expensive.
