12306.cn's verification security test

As the annual Spring Festival travel peak, known as Chunyun, approached, online tickets buyers felt upset as the 12306.cn, the only official website allowed to sell train tickets, adopted a verification security test in which the users needed to click certain pictures among the eight images to log in.

It was supposed to be easy, but due to the fuzzy images travelers struggled to answer the questions correctly.

Frustrated Internet users edited a series of verification pictures to ironically mock the system for failing to do the job that quickly become an Internet meme.
