Reborn in 1988

Cai Lan is reborn and returns to her childhood. Looking at her little childhood sweetheart and seeing that nothing has begun yet, she feels that anything is possible. Time to work hard, then. But first, she still has to recite "a, o, e" with the teacher... "Hey, that's not fair! Don't you know he's my underling?" Cai Lan steps in front of the little boy, facing a much taller boy without a trace of fear. "Lanlan, Lanlan." Cheng Lu tugs on Cai Lan's sleeve. "He's my cousin." Cai Lan turns around. "Your cousin?" "Bro, I think you're wasting your time doing nothing over the holidays." Cai Lan wears an ingratiating smile. Cai Lei gives her a sidelong glance. "So what should I do?" Cai Lan pulls out a big handful of meat skewers. "Let's sell barbecue." "We received a tip from the public and raided this counterfeiting operation." Cai's father nods. "Good work. We should also raise awareness afterward, and commend the people who reported it." The young officer grins and points to the little girl trying to sneak out of the office. "This member of the public is your daughter." Theme: When we return to the past, what do we want to change, and what do we hope to gain? Can we get back everything we missed?
