I thought this was common knowledge by now, but apparently some people don’t know that both Vein and Xia Fei are ambidextrous.
It’s more obvious with XF:
Xia Fei uses his left hand to draw and write in his PV:
Left hand to point, but right hand to do the shush gesture
Right hand to shake CXS’s hand and hold his beer
Left hand to pound on the table, but right hand to hold chopsticks
Left hand when on the phone with Vein/LX:
But right hand during his flashback:
Oh, and also right hand to “defend” ShiGuang
As for Vein’s hands, I’ve listed all instances of them from the show here (except for the latest episode). As many have noticed, he used his left hand more in episode 1. He prefers his right the rest of the time—except for when he flicked XF on the forehead and patted his head. He used his left hand then (his fan was on his right).
Then in Bloody Storm, we have this:
Left hand to topple the wine glass but right hand for everything else
Edit: also to topple the mahjong tile
Now, Xia Fei being ambidextrous is no surprise because everything about him comes in two’s (yellow-black hair, possibly half Chinese, his character color being the liminal traffic light Yellow, both red and green traffic lights in the ED turned on while his ad plays in the background, second survivor in a fire that was said to have only one, etc.)
As for Vein, I’m not gonna jump into conclusions since his own episode (the finale) is yet to air. However, I have an inkling that how he uses his hands has something to do with his ability (which I believe he has; it just hasn’t been revealed)
Lastly, Hands are an important thematic element in Yingdu:
I haven’t gathered my thoughts about it yet, so have my Discord rambling for now.
But bottomline is that Hands, in Yingdu, are a means of forming/rejecting bonds. VeiFei being able to use both their hands must have some thematic significance.
A reason like “Vein is actually XF in episode 1” just feels so lame, tbh. If this were a normal season, then whatever, but Yingdu has been more on Themes than Plot/Logic. Additionally, it has been focused on creating Emotionally Satisfying moments over mentally stimulating ones...
Vein/Xia Fei using their hands have to mean something on a deeper emotional level for it to align with the themes of relationships that Yingdu heavily emphasizes on
