Ni Hao, Kai-Lan

In season 2, she says this phrase in Mandarin Chinese as well.

Other aspects generally featured in episodes are 11 minutes of interactivity, a target word that is repeated multiple times, a few words of Mandarin Chinese vocabulary, and Kai-Lan saying, "You make my heart feel super happy" at the end of each episode, before saying goodbye.

Ni Hao, Kai-Lan introduces its viewers to the Mandarin Chinese language, along with elements of Chinese culture and values, and intergenerational families (e.g., Kai-Lan and her relationship with Ye-Ye).

In the season 1 finale, it is revealed that they all live in California.

Each episode is based around a series of events during Kai-Lan's day, along with obstacles that she and her friends are forced to overcome (with "assistance" from the viewing audience) relating to riddles, playing games, and working together.

The episode always ends with Kai-Lan successfully helping her friends and everyone gets along.
