As Koo Jun-yup, husband of the late Taiwanese actress Xu Xiyuan (also known as Barbie Hsu), mourns her passing, a wave of criticism has emerged online. Among those condemning him is Chinese director Wang Ziqi, whose remarks have ignited heated debates. In response, prominent Taiwanese ophthalmologist Huang Youjia stepped forward to defend Koo, launching a scathing critique against malicious commenters.

According to reports from Taiwanese media outlet ET Today on February 9, Wang Ziqi left a comment on Koo Jun-yup's social media, calling him "a hypocritical person."

Claiming to be a devoted fan of Xu Xiyuan, Wang Ziqi expressed sorrow over her passing. However, his sympathy did not extend to Koo, as he harshly criticized him, stating, "I cannot accept the hypocritical and ruthless statement from this old Korean man. Instead of showing genuine grief, all I see is calculation."

Wang's comment quickly attracted backlash, with some netizens questioning his moral authority. "What responsibility have you taken in your own past marriage?" one user asked. Defending himself, Wang shot back, "Do not attack me for my previous marriage. After my divorce, I left home. A bad marriage may hurt you and, at worst, ruin your reputation."

At the center of the controversy was Koo Jun-yup's heartfelt tribute to his late wife. On social media, he posted a video of himself playing a melancholic piano piece with the caption, "I will love you forever." However, despite his public mourning, some netizens continued to scrutinize his role in their marriage.

Critics questioned, "What responsibilities did Koo Jun-yup actually take on during their three years of marriage? How much time did he even spend in Taiwan? Did he share any of the household's financial burden?"

As the online attacks escalated, Taiwanese ophthalmologist Huang Youjia strongly condemned the negative comments, publicly calling out cyberbullies. Huang took to Facebook to share screenshots of the harsh criticisms and commented, "These people are comparing levels of intelligence on the internet. Is it because they don't read books? Do they stay home so much that they never visit museums?"

He continued, "It's like poor people arguing over who has more money, or talentless individuals debating who is more sophisticated. Even ugly people compare appearances. This is ridiculous."

Huang further lashed out, saying, "Do pigs realize they are eating pig feed? Do people who read nothing but trash know they are not reading the works of literary masters?" He called out netizens who, in his view, "stay silent in real life but tear others down online." His remarks resonated with many, garnering widespread agreement among Taiwanese internet users.

Meanwhile, as fake news spreads regarding Xu Xiyuan's passing, Koo Jun-yup has also been fighting against misinformation.

Rumors alleging that Xu Xiyuan's younger sister, Xu Xidi (Little S), was happy before her sister's passing, and speculation that Koo had taken out a life insurance policy on Xu Xiyuan, have fueled public outrage.

Koo Jun-yup firmly denied the allegations, stating, "They are creating fake news about insurance and money just to attack my family. It terrifies me to think that such terrible people truly exist."

"Please, let Xu Xiyuan rest in peace. I am begging you," he pleaded.

Regarding inheritance matters, Koo Jun-yup clarified, "This wealth was earned through my wife's blood, sweat, and tears to protect her loved ones. I have no intention of claiming any of it and will entrust everything to my mother-in-law."
