（Xinhua News）What kind of vehicle will you choose when traveling between provinces？ Many people may like traveling by train because it's safer and cheaper． Now the high﹣speed railways have connected eastern and western China as well as the south and the north．

A new high﹣speed railway opened on Sept． 10th， 2016． It connects Zhengzhou in Henan Province with Xuzhou in Jiangsu Province． With this railway， China's high﹣speed railways are over 20，000kilometers long． It is the world's longest and makes up 60percent of the world's total high﹣speed railway lines．

Besides length， China also does better in speed． China is the only country with trains running at 350kilometers an hour， such as the Beijing﹣Tianjin and Beijing﹣Shanghai high﹣speed railways．

With these surprising numbers， it is easy to forget that China wasn't the first in the high﹣speed rail game． Japan started 50years ago， while Germany did 20years ago． China only began to build its high﹣speed railways 14years ago．

China's high﹣speed railways are developing fast now． Behind it， there is the country's growing need for transportation． According to Xinhua News， China's high﹣speed trains gave 961million trips to people last year．

"The high﹣speed railways not only bridge the distance， but connect people， information and goods．" said Huang Xin， an official from the China Railway Corp．

Yet， China's building of high﹣speed railways is still going on． China plans to have 38，000kilometers of high﹣speed railway by 2025．
