Ni Hao, Kai-Lan is a video game and the online game series based on the Nick Jr. tv show Ni Hao, Kai-Lan. Ni Hao, Kai-Lan (simplified Chinese: 你好, 凯兰; traditional Chinese: 你好，凱蘭; pinyin: Nǐ hǎo, Kǎi Lán!; Hello, Kai-Lan) is an American animated (anime-influenced) interactive children's television series which premiered on Nickelodeon on November 5, 2007, and on Noggin (now Nick Jr.) on December 15, 2008. It also premiered on the Canadian television channel Treehouse TV.
Ni Hao, Kai-lan is based on the childhood memories of the show's creator Karen Chau growing up in a bicultural (Chinese-American) household. “Ni hao” means “Hello” in Mandarin, and Kai-Lan is the Chinese name Chau was given at birth, which was later anglicized to Karen. It was also based on the classic short series Downward Doghouse.
The setting of the show appears to be China or Ancient China throughout most episodes. However, it's revealed in the Season 1 finale that they all live in California, possibly in Chinatown. It appears most of the characters (except Kai-Lan, YeYe and GuNaiNai) aren't Chinese, though this could be to introduce diversity. Ni Hao, Kai-lan introduces its viewers to the Mandarin Chinese language, along with elements of Chinese culture and values, multiculturalism (through the diverse backgrounds of Kai-lan's friends), and intergenerational families (e.g., Kai-lan and her relationship with Ye Ye).
Episodes generally feature breaking the fourth wall, 11 minutes of interactivity,a target word that is repeated multiple times,[ a few words of Mandarin Chinese vocabulary and before saying goodbye (at the end of each episode), Kai-lan says, "You make my heart feel super happy!" Later installments added Kai-lan saying this phrase in Mandarin after she said it in English: "Ni rang wo hao kai xin!"
