Freddy Lim Tshiong-tso (Chinese: 林昶佐; pinyin: Lín Chǎngzuǒ; Tâi-lô: Lîm Tshióng-tsò; born 1 February 1976) is a Taiwanese politician, musician, and independence activist.

[9][10] With fellow Chthonic member and wife Doris Yeh,[11][12] Lim started the Taiwan Rock Alliance, and as co-founder of The Wall, helped organize two music festivals, Formoz and Megaport.

[19] Chthonic was billed to play on the second day of the 2018 On the Pulse of Music Festival, but the performance had to be cancelled because Hong Kong Immigration Department refused to grant Lim a visa.

In the letter, officials stated that a person seeking to enter Hong Kong for employment "should, amongst other things, possess a special skill, knowledge or experience of value to and not readily available in the HKSAR", and that the immigration Department was not satisfied that Lim met the criteria.

[23] The next month Lim declared his candidacy for the 2016 elections, aiming to contest the Daan District legislative seat held by Kuomintang incumbent Chiang Nai-shin.

[24] A few weeks later, Lim ceded the race to Social Democratic Party candidate Fan Yun [zh],[25] choosing instead to run against incumbent Kuomintang legislator Lin Yu-fang in the Zhongzheng–Wanhua constituency.

[30][31] On 3 October 2018 during the FNDC session, Lim proposed to re-examine the 1987 Lieyu massacre files in the military archive to render a formal apology to the victims' families through the Vietnamese Representative Office,[32][33] but Minister of National Defence, General Yen Teh-fa disagreed, claiming that troops followed the standard operating procedure in effect during martial law, and have been court-martialed; later the Ministry of National Defense issued a written response stating that the case "could not be processed further, as it is too difficult to identify the deceased after so much time has passed," which serve as the sole statement of the ROC government for the massacre in 31 years after martial law was lifted in 1987.

[38] The Central Election Commission announced on 10 August 2021 that a petition to recall Lim had gathered enough support, one percent of the eligible electorate in his constituency, to pass the first stage.
