I just found out my estranged little sister became one of the biggest “it girls” in China and I don’t know how to process it

I apologise if this is a little disorganised; I really don't know where to begin. I'm a 27F with Chinese ancestry who grew up in Australia. Our parents are entirely Chinese immigrants; they are quite traditional, rigid, and all that. Growing up, my younger sister, 22F, and I were never close. Not adversaries, but also unquestionably not partners. To be completely honest, neither of us was ever deemed "pretty" as children.Not by Chinese or Australian standards. I've always had awkward features, a huge forehead, and a very long face. Even though my sister was marginally more attractive than I was, she was still, at most, mediocre. Our "thing" was never appearances. The "smart one" was me. The individual who did well in school, maintained my focus, and received good grades. That was everything my parents hoped for. In contrast, my sister was more interested in social issues, fashion, gossip, and makeup.Parents like them don't really value typical things. They were always criticising her for being superficial, squandering time, and failing to consider her future. My sister completed her final exams at the age of eighteen when I was twenty-three. She completely destroyed them. Like, a very low score. The kind where even entry-level jobs were difficult to obtain and college was essentially off the table. Our family had a huge meltdown as a result. Allegations, sobbing, screaming matches,the whole thing. My parents were devastated and incensed. My sister felt totally unwelcome and like a failure. Next she simply walked away. Shortly after, she relocated to China. No fitting closure, no grand farewell. After that, I didn't really speak to her again. For a while, my parents tried messaging and calling, but they eventually gave up as well. Life simply continued. I didn't give her much thought, which may sound chilly, but we never bonded in that way. Now fast-forward to the present. I have a 5-year-old daughter, i am married, and lead a fairly typical, secure life. Comfortable, but not glamorous. the kind of life you quietly strive for. A few weeks ago, I was doom-scrolling on Instagram late at night while half asleep, just like everyone else. I saw this video of a girl who, to be honest, didn't look real. Like, gorgeous like a goddess. Perfect face, crazy styling, self-assurance, everything. The kind of person you simply ignore because they seem so phoney. However, I did notice the name. The name of my sister. I initially thought there was no way. Coincidence, common name, etc. However, I clicked because something didn't feel right. same name. identical birthdate. The same background: Chinese, raised abroad, and returned. The same tale. She was the one. I descended into a rabbit hole. It appears that she became more than just "an influencer." She is enormous. Like, one of China's biggest it girls. millions of supporters. brand agreements. edits by fans. She is referred to as a beauty icon.She doesn't resemble the awkward adolescent I grew up with at all. She either underwent extensive plastic surgery or had the greatest makeover in human history, most likely both. I was totally numb as I sat there looking at my phone. I have no idea what I'm feeling. It goes beyond simple jealousy. It's a shock. incredulity. A strange sorrow. Perhaps a little rage. For example, how does the sister who was written off, failed school, and vanished return as this? I do have a nice life, but there is also a part of me that feels terrible for even considering this. I adore my spouse. Above all, I adore my daughter. However, after being the family's "failure," seeing her so widely loved and visible has caused me more mental distress than I anticipated. It's been years since we last spoke. It's likely that she doesn't even consider me. And now I am, lying awake at night, reliving our early years and pondering how two members of the same family could have gone down such radically different paths. I'm not sure why I'm posting this. Perhaps all I needed to do was let it out. I'm not sure if I should get in touch. I'm not sure if I want to. I simply know that discovering her in that state revealed something I had previously believed to be hidden. If you have read this far, I appreciate you.
