Two Pairs of Twins in a Women's Basketball Team

Nine people out of ten may give the wrong answer if they try to distinguish Sun Yiping and SUN Yiwei from their photos. Walking in the street, they are always the attracting focus with tall figures and same good looking. Are there really telepathy between twins? Teammates have tested repeatedly. Once in an outing, a teammate stood between Ma Xiaoting and Ma Xiaolin and had Ma Xiaoting guess the gestures Ma Xiaolin chose. The results were accurate, "2" Teammates tried again, and she blurted out the right answer "1" unconsciously, incredible to teammates. Is it affiliated or long-term coexisting mutual-understanding? Ma Xiaolin can't tell either.
