I was born in 1990. Am I born after 90? Also, I was supposed to be a Gemini, but I gave birth to a cancer late. What constellation should I be?

Constellation is a credible thing, but I can't believe it (shame, my classmates gave me a nickname: constellation expert, because I actually believe it). I'm also born after 90, but I'm mixed up with the born after 80 (all my classmates are 88 and 89). I even flaunt myself as a post-90s generation, because I am young, and the post-90s generation is not as impetuous as everyone thinks, hee hee. . . Secretly pleased. . . Like me, you want to do everything perfectly, and you often face everything alone, but I am a Taurus, and sometimes I feel like a Gemini, because I am not as enterprising and steady as Taurus. I'm actually glib, like Gemini, but I love food, men and money. . . . . Self-confessed taste is also very high and unique, much like Taurus, tangled. . . . . . . In the end, I struggled with the result that my original date of birth was Taurus, so I am Taurus. This is god's arrangement, let fate take its course!
