What is the difference between a Bei Bei and a Podeagi?

A Bei Bei is shorter in width and wraps over both shoulders (view in pictorial instructions). It can be crossed in front or not. I think it is more comfortable not to cross the straps in the front. Traditionally the Podeagi wraps around the chest and is longer in width so it can cover the entire chest. It can also be worn over the shoulder, but I have never tried this. Traditionally the Bei Bei comes from Southern China, and the Podeagi comes from Korea.
