Carry does refer Cherry as jie jie (姐姐) or older sister. The two do look very much alike. Their eyes, jaws, noses and body shape are very similar. They are not twins but definitely sisters. If you want to get nerdy, I would say they are at ~3 standard deviation confidence level sisters and only at VaR with α = 0.05 that they are not. IF you're into sisters like me, book a long session with these lovely sisters, pop yourself a Roman pill and enjoy the ride. Afterwards you can check off the box in life accomplishments for experiencing a ménage à trois with two real Sichuan sisters.
