Great Tang: Mistaken for the Crown Prince by Empress Zhangsun from the Start

Li Yu transmigrates to the Tang Dynasty and nearly starves to death in poverty, until a young man named Li Wang saves him.

They have similar birthmarks and take to each other at once, so they swear brotherhood and become sworn brothers.

But Li Wang suffers from an incurable illness and dies young, leaving behind a jade pendant and asking Li Yu to find his parents and fulfill his final wish.

One day, Li Yu sets out to travel the world and find Li Wang's parents, hoping to do his part in honoring his sworn brother's filial duty.

Unexpectedly, a middle-aged man arrives with his critically ill wife, asking to use the place for her treatment.

By a twist of fate, Li Yu saves the woman, who turns out to be the very mother Li Wang was separated from years ago. The middle-aged man is his father.

Because of the birthmark on his arm and the keepsake, the couple mistake Li Yu for the eldest son they lost and who grew up among commoners.

And that couple are none other than the emperor and empress. Thus begins a prosperous age in Chang'an...
