3.14（双节日）：白色情人节white day+国际数学日Pi Day π节

今天是3月14日是白色情人节。“白色情人节”最早起源于三世纪时的罗马。相传罗马皇帝在2月14日救了一对因为原本因违反恋爱结婚禁令而要被处死的恋人，罗马皇帝为了纪念这一天而设立了情人节。而在一个月后的3月14日，这对获救的恋人宣誓恋情将至死不渝，为纪念这一天，于是另订为白色情人节。

Today is March 14th, the White Valentine's Day, which originates from Rome in the third century. It is said that the Rome empire saved two lovers who disobeyed the ban on love and marriage and should be sentenced to death in 14th,February , and in order to remember this day, the empire set it as the Valentine's Day. One month later in 14th, Marth, the saved couple swore that their love would last forever until their death, so to the memory of this day, the White Valentine's Day was set.
