I'm back again, from Hefei to Shanghai

Three days with nearly one day spending on the trains, crowded train....unbearable....

So it suddenly occured to me something about train ticket. Once there was an article saying in China if we people are late and miss the train then the ticket is useless and the money will never return to us but what if the train is late?? then we have to wait no matter how long it will delay...... 

We know that China has a huge population and most of them are rural migrant workers, which exerts great pressure on the transportation system. But on the other hand, train is the best option for the rural migrant workers, it is cheap and safe. But there is still a lot of space for the train ticket system to improve.
