How Much Sorrow Do You Have, also known as The Real Warrior in some countries,[2] is a 2005 Chinese historical drama produced by Beijing HualuBaina Film & TV Co.

Essentially a soap opera, many relationships are fictionalized, but recorded historical events including the Conquest of Southern Tang by Song are followed relatively faithfully.

Over 60 historical characters appear in this series, including 9 monarchs of 5 different states (Later Han, Later Zhou, Later Shu, Song dynasty and Southern Tang).

Zhao Kuangyin and Zhou Ehuang fell in love at first sight and they planned to visit Southern Tang together.

After Zhao Kuangyin conquered Southern Tang and the other kingdoms, he spared Li Yu and his family.
