On 19 August 2009, Chin met with the General Secretary of the Communist Party of China, Hu Jintao. At the meeting, General Secretary Hu expressed his deep sorrow and condolences for the typhoon victims in Taiwan to an actor-turned-politician Kao who led a delegation of her fellow ethnic minorities in Taiwan to visit the mainland.

In 2006, it was reported by the Taiwanese media Next Magazine that she had a long and lasting extramarital affair with the Minister of the Interior Lee Hong-yuan between mid-2000s and early 2010s.

Chin was elected into the Legislative Yuan of the Republic of China (Taiwan) in December 2001, and re-elected in 2004, 2008, 2012, and 2016, all in the Highland Aborigines electoral district.

She is also associated with the Pan-Blue Coalition and harbors pro-Chinese unification and anti-Japan views.

Since entering the Legislative Yuan after elected in the 2001 Republic of China legislative election, Chin has been noted for her outspoken views, traditional Atayal costume and face paint in the shape of traditional Atayal tattoo work reserved for married women. Chin has also been tightly associated with the Pan-Blue Coalition, especially in close cooperation with the People First Party. She is also noted for her anti-Japan and China-friendly standpoints, and even protested in front of the Yasukuni Shrine in an effort to remove the enshrined spirits of Taiwanese Aboriginal soldiers who died fighting for the Japanese army during World War II, as well as sued Japanese Prime Minister Junichiro Koizumi for visiting Yasukuni Shrine. (These events were retold in the 2007 documentary film Yasukuni.)

They later separated in 1993, and still remain good friends. Chin and Ho agreed that if they are still single by the age of 60, they would spend the rest of their lives together.
