Look! There are thousands of people waiting to buy tickets home in the railway station. Each time when Spring Festival comes, buying tickets of train trip would be very hard. And things seem to be getting worse and worse, although we have greatly increased the mileage of railway network and speeded up trains. Why? It’s because too many people want to go back home to spend Spring Festival with their family. Many people become angry with the Ministry (部)of Railways.

They wonder why it is hopeless for them to get the tickets from the railway station(火车站)Instead, they sometimes can only buy them from ticket scalpers (票贩) at much higher price.

The Ministry of Railways estimated(估计)that about 188 million passengers would travel by train during the 40-day peak (高峰) period surrounding the 2009 Spring Festival holiday. The number of travelers will be 8％ higher than that of 2008. This problem even drew the President Hu Jintao’s attention. He wrote a note to Liu Zhijun，Minister of the Ministry of Railways, asking him to take action to improve passenger convenience. Afterward, officials from the Ministry of Railways said they would try their best not to let any ticket-buyers spend Spring Festival at the railway station.
