In the eleventh year of Zhenguan, the two-and-a-half-year-old Princess Li Mingda of Jinyang - nicknamed "Si Zi" - was chasing butterflies by the Taiye Pool and fell into the water. A mysterious beam of light swept her away. When she opened her eyes again, the palace in Chang'an disappeared, and she landed in Yudu, Jiangxi in 2025.
The little princess, wearing a Tang Dynasty Ruskirt and a double bun, called her cell phone "Demon Mirror" and her car "Iron Monster" and broke into the Hakka girl Chen Xiaohe's teahouse with the words "I'm hungry, have you eaten?" After a bowl of tea, she said three words in a milky voice - "Li Shimin", which shocked the whole audience.
Retired old teacher Liu Bo noticed something strange from her accent, clothes and polite way of speaking. A "New Book of Tang" revealed the truth: this two-and-a-half-year-old girl really came from 1,300 years ago.
But the most heartbreaking thing is what Sizi stood by the Yudu River, looking at the sunset, desperately holding back tears and shouting - "Aye, where are you?"
Thirteen hundred years is too far away, so far that even Aye could not find her even though he searched all over the world. But she remembered every word Aye said: The princess is not allowed to cry. The place where the sun sets is the direction of home.
A little princess from the Tang Dynasty, in the small town of Yudu in 2025, missed Aye while bravely moving forward. This is a story about getting lost and searching - where the sun sets is the direction of home, and where the sun rises is the direction of a new beginning.
