Known as "xiao la jiao" or "little hot pepper" for her straight-talking style, she is often compared to former Alaska Governor Sarah Palin.

[3][4] Her father, Hung Zi-yu (Chinese: 洪子瑜), born in Yuyao, Zhejiang, was a victim of political prosecution during the White Terror in Taiwan.

A reporter from The China Times called Hung "the talkative little genius" when she won first place in a citywide storytelling contest as a fifth grader.

[citation needed] Hung almost lost her second election term of Legislative Yuan on 19 December 1992 to Jaw Shaw-kong in the same constituency.

KMT lost majority of the seats in the local elections on 29 November 2014, resulting in the resignation of Party Chairman Ma Ying-jeou, with both first and second Vice Chairmen declined the acting position.

[17][18] During the opening remark of the 4th Straits Forum held in Xiamen, Fujian, in June 2012, Hung, in her capacity as Vice Chairperson of KMT, said that although mainland China was bigger and stronger, the greatest appeal that mainland China has for Taiwan is not only growing competitiveness, but also respect and goodwill given to the people of Taiwan.

[19] During the opening remarks of the 6th Straits Forum held in Xiamen, Fujian in June 2014, Hung said that she hoped that both sides will cherish their increasingly close links and continue mutual dialogue and exchanges, because by doing so it will be possible to inject a new energy into cross-strait relations.

She added that the forum remains full of enthusiasm and vitality despite the recent setback on the signing of the Cross-Strait Service Trade Agreement from the Sunflower Student Movement.

[20] She did acknowledge the widening gap between the rich and the poor in Taiwan as well as the younger generations dissatisfaction towards the government that also exist in many other countries due to the global trend of moving towards free trade.

[23] She was officially nominated as the KMT presidential candidate during the National Party Congress on 19 July 2015 at Sun Yat-sen Memorial Hall in Taipei.

During an interview with a local radio station, Hung stated she would take the interests of the people into account, as well as the ROC constitution, when making decisions.

[29][30] President Ma Ying-jeou has supported this view, calling it no different from his own "one China, different interpretation" based on the 1992 consensus,[31] though Kuomintang chairman Eric Chu has opposed it.

[34] On 26 July 2015, the spokesperson of Hung's campaign team Jack Yu (游梓翔) said that he would tender his resignation on 1 August 2015 to return to his teaching position at Shih Hsin University.

[36] Due to her poor performance in polls,[37] 91% of delegates at the congress, held on 17 October, chose to replace Hung as KMT presidential candidate.

[39] Hundreds of Hung's supporters gathered outside Sun Yat-sen Memorial Hall to protest the party congress being held inside the building.

[40] On 22 October, Hung announced that she would return all campaign contributions made since 23 September, a total of NT$11.83 million, to 2,633 donors.

Hung rejected this offer in November 2015, announcing her intention to stay with the KMT, but not to run a legislative reelection campaign in 2016.

[48] On 30 October 2016, Hung led a delegation to attend the 11th Cross-strait Peace Development Forum which was held on 2–3 November in Beijing.

The delegation included Jason Hu, Steve Chan, Huang Ching-hsien (黃清賢), Alex Tsai, Chang Jung-kung (張榮恭) and Wu Bi-chu (吳碧珠).

In August 2019, Hung stated that she would contest the 2020 Taiwan legislative election, in the newly formed Tainan sixth district.

[53] She accused the United States of fabricating lies about Chinese repression of Uyghurs in Xinjiang while on a trip sponsored by the Chinese government, claiming "The US and some Western countries have fabricated lies about the so-called ‘forced labor’ and ‘genocide’ in Xinjiang to undermine China’s internal unity."
