The pro-green artist Ke Yulun on the island was dissatisfied with the netizens surnamed Xu leaving a message on Facebook, "Okay, Ta Green Class" and filed a civil lawsuit for . asked for compensation of 200,000 yuan (New Taiwan dollars, the same below). After the trial of Taipei District Court, , believed that Xu was an appropriate comment on matters that could be publicly evaluated, so he made a good statement and ruled to reject Ke's request, Xu was deductible, and could appeal.

Mainland " China Daily " reported that Ke Yulun once had "Taiwan independence" words and deeds, and supported his father's film director Ke Yizheng's "Taiwan independence" position, which also led to the release plan of the movie "Johnny Keck" starring him in mainland China in 2018. Some mainland media have previously reported that after Ke Yulun was banned by the mainland, he quickly turned to the Democratic Progressive Party and even became a flank of the cyber army.
It is understood that on October 18 last year, Ke Yulun left a message on his Facebook fan page, "I can only say that I wish the Taiwan entertainment industry a good time to lift the strictness as soon as possible", while a netizen named Xu replied "Okay, Ta Green Class" below; Ke publicly pointed out that he had zero tolerance for the three words "Ta Green Class" and asked a lawyer to file a civil lawsuit, demanding Xu's compensation of 200,000 yuan.
Taipei District Court believes that Xu's term "Ta Green Class" certainly means that Ke is "green camp and its extreme supporters", but Xu uses Ke's statement to "bless the Taiwanese entertainment industry to relieve strictness" as the basis, and jokes that Ke's Facebook reply has a strong political ideology and is a supporter of the Democratic Progressive Party with a deep political tendency. The judge pointed out that the context of the posts and replies of Facebook , as well as the context of these remarks, can be regarded as a subjective expression of opinion and a high-value political speech. After weighing Xu's freedom of speech and Ke's right to reputation, it was determined that Xu's remarks did not infringe on Ke's right to reputation. Ke requested no reason to pay 200,000 yuan in spiritual comfort and comfort, and the judgment was rejected.
In response to this, the island media person Zhu Kaixiang posted a message yesterday: "The court certified Tianzi No. 1 'Tagree Team Soldier', Dongdong (001), Ke Yulun." It is even more harsh: "The specialty of military science: known to use fire." It is full of irony.
