Do you know Weibo? Do you write a Weibo? If you don't, you are "out"! Weibo means microblog. People may spend muchtime writing a blog, but it takes a little time to write a microblog.Why? Because every message on a microblog is less than 140 words.
Microblog started in the USA. It came to China in 2009 andit has developed very fast. In 2011, the number of Chinesemicro-bloggers grew to 300 million. Now, more and more people are interested in writing microblogs. For manymicroblog users, it is a great way of learning the freshest news,talking with friends and sharing different kinds of information, including news, daily life, pictures,music and so on. Many stars and famous people also write microblogs and share good things with theirfans.
It is easy and fast to send a message on a microblog. However, this can also lead to problems and even cause panic . For example, when thebig earthquake and tsunami hit Japan in March, 2011, messages like " Salt can protectpeople from radiation" were hot on microblogs. It soon caused a crazy buying of salt. Later people realized it was just arumor (谣言).
In a word, microblog plays a new role in the life of Chinese people.

早在私商发行期间，交子的图案有“屋木人物”，用朱、墨两色，还有各私人铺户的押字，“各自隐密题号”，以防伪冒。这种办法，近世纸币亦予采用，而其防止伪造的各种记号，自然要比交子精密得多。此外，宋朝纸币开始大约是用木版印刷，后又改用铜版印刷，这也是印刷史上的重大进步。交子的币面价值，最早限于1贯和10贯，而在发放时临时书填，这与近世支支也有相似之处。宋仁宗宝元二年（公元1039年），改为只发行5贯和10贯两种交子，宋神宗熙宁元年（公元1068直），又改为发行1贯和500文两种交子，币面价值由临时书填改为定额印刷，这也是纸币史上的一个重大进步。
