A computer program that writes love letters has become a runaway success in China.

The 'Magic Love Letters' program has already been downloaded more than 20,000 times.

The programmers say it can write more than 10,000 different love letters, reports Chutian Daily.

Users only need to type in sender's and recipient's names and the number of lines they want.

It also contains more than 100 classic love letters, which can be adapted by changing the names.

Professor Zhou Yunqing, of Wuhan University, said: "It's not a bad thing. With this software, some people can better express their inner feelings without misunderstanding."
