Today is Valentine's Day. May 20th every year is Valentine's Day on the Internet. On May 20th, 2004, a group of single young men from China People's Liberation Army Information Engineering University created a way to find someone online, which they called 520 Love Finding Day. Gradually developed into valentine's day. The ritual sense of Valentine's Day includes customizing love certificates, promising each other a lifetime of happiness, giving gifts to each other, having a big meal together, and going for a walk in the park after dinner.
