When we hear the word "mythology," most of us think of ancient stories—tales of heroes and gods, and mythological creatures that exist only in movies and books. But what if some of these myths aren't just stories? What if they're remnants of a lost culture? My fascination with Sanxingdui began in childhood, spawned by the legends like Nezha. Yet, the more I read, the more I realized that those sky-reaching immortals we heard about as kids might be based on something real—something just beyond the curtain of time, waiting to be unearthed. To uncover the truth, I invite you to join me on the journey into the mysterious world of Sanxingdui, where bronze trees reach up to the heavens, golden birds carry the sun, and myth and history embrace. 05后深圳国际部学生；深中toastmasters社社长 This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
