孙颖莎为何不站C位？刘国梁为何不与日本队握手？原因不言而喻（孙颖莎为何未站中间？刘国梁为何未与日本队握手？背后缘由一目了然）

Exploring handshake protocols in sports

I should outline factors influencing handshake decisions: team protocols, camera framing, organizer instructions for medal placement, timing issues, and health protocols such as COVID measures. It’s vital to suggest checking full broadcasts or multi-angle footage to avoid context issues with viral clips. I also need to maintain a neutral tone and avoid political discussions, focusing instead on sports etiquette. I wonder if the user has a specific clip in mind they'd like to verify.Clarifying handshake details

First, I should confirm which match or photo the user is referring to, as rules vary by event. The C position is usually determined by placement rules set by organizers or sponsors. I can clarify that handshake sequences often follow the referee, opponent, and coach, but various factors can affect this, like camera angles or health protocols. I should mention that misleading clips can omit important context, and I can help analyze specific footage if they provide links or images.
