Ting-Ting, Su, and Mei are The Emperor of China's three daughters from Disney's 2004 film Mulan II, sequel to the 1998 film Mulan. They are sent on a mission to marry the sons of Lord Qin in order to form a complete alliance between China and the kingdom of Qui-Gong.
Princess Ting-Ting (婷婷公主)
Ting-Ting's the oldest and the tallest daughter of the Emperor, and purple is her signature color. She appears to be the smartest and the most mature of her sisters, but is carefree at heart. After Mushu's attempt to make the carriage slide down, she first helps her sisters escape, but her foot is caught when she tries to get out. However, she is saved by Ling. When she hears his jokes, she thinks that they are funny but tries not to laugh, as she thinks she has an embarrassing laugh because she snorts.
Princess Mei (小梅公主)
Mei's the middle daughter of the Emperor and is in the middle of her sisters' heights, and pink is her signature color. She's in love with Yao because she thinks that he is good-looking and gentle at heart even though he has such a hot and very violent temper. Mulan convinces her that her duty is to her heart and she believes that this is true. When Yao wins a wrestling fight, he chooses a stuffed panda bear and the two share it together. She is considered a slight damsel-in-distress, as she has been kidnapped by the enemies of China when the heroes are knocked down during the fight, but she is often saved by her friends. She is passionate, brave, and caring.
Princess Su (素素公主)
Su's the youngest and shortest daugher of the Emperor, and orange is her signature color. Her favorite thing to do is gather food from the trees. She likes to spend time with Chien-Po, who also enjoys food like her. When the carriage is damaged and the fruits float in the water, she picks them up and is saved by Chien-Po, too. She is bright, childish, and cheerful.
In the movie, the Emperor calls upon Mulan and Shang to escort his three daughters across China to be betrothed to Lord Chin's three sons so that an alliance can be formed with the kingdom of Qui Gong. The task has to be completed in three days or the proposed alliance will crumble and the Mongols will destroy China. Mulan and Shang set out with Yao, Ling, and Chien Po to safely escort the princesses.
The princesses are upset about their arranged marriages (even though they love their father very much and don't want him to be disappointed with them), and fall in love with Yao, Ling, and Chien Po instead. They eventually go against Mulan's orders and Shang's wishes after singing about "I Wanna Be Like Other Girls". Later, due to Mushu's scheming, the three soldiers take the princesses to a village, where they impress them. Mulan soon discovers them and accepts the fact that the princesses are in love with the soldiers. Shang, however, isn't as pleased when he too finds out about them and angrily reprimands the princesses, but also harshly snaps at Yao, Ling, and Chien Po because they utterly disobeyed him.
Later, while traveling to Qui Gon, the group is attacked by bandits. Mulan and Shang are successful at saving the princesses, but Shang ends up sacrificing his life by falling into a river and is assumed dead. Mulan sadly continues her journey alone with the princesses. Since the princesses don't want to be in arranged marriages (and Shang is supposedly dead), Mulan offers herself as a bride in their stead, and Lord Qin willingly offers his eldest son, Prince Jeeki, for Mulan to marry. Thanks to the interference by the mischievous Mushu, who pretends to be the "Golden Dragon of Unity," Mulan's marriage is stopped when Shang is revealed to be alive. Mushu orders that the princesses be freed from their vows and are allowed to marry whomever they please, thus keeping the unity between the two kingdoms intact.
- In the song "A Girl Worth Fighting For" (redux), their marriages to Yao, Ling, and Chien-Po are foreshadowed at certain parts other then their clothes colors.
- Ting-Ting has the same singing voice as Pocahontas.
- Su appears to be a speed reader when reading Mei's letter.
- In most ancient (and even some modern) East Asian cultures, a noble woman's bare feet were considered almost as private as her genitals. A princess would never have extended her bare foot to a soldier, no matter how gallant.
- The sisters' heights are based off the voice actors' heights. Su (played by Lauren Tom) is 5'1, Mei (played by Lucy Liu) is 5'3, and Ting-Ting (played by Sandra Oh) is 5'7.
