大家Pi日快乐！

非华人朋友包括几位中学生，根据美国军训曲调改编，做了一个《圆周率Pi进行曲》的动漫。

该曲调是美军操练时唱的，不同军兵种，不同教官填的词不同，而且有领唱（教官）和附和（学员），但是曲调一致。

心意让人很感动，希望大家也喜欢。

It is a March song by a team of teenager robotics students just for fun and led by their coach who learned this tune while in the Army years ago. It is intended to be an easy way to remember 55 digits of Pi, which is essential knowledge for everyone.
