1. Who Is Guo Shu Yao?

Guo Shu Yao (郭書瑤), also known by her nickname Yao Yao, is a Taiwanese actress and singer who rose to fame in the early 2010s. With a bubbly personality and a positive public image, she’s become one of Taiwan’s most recognizable media figures.

She has no political background and has never been involved in activism. This is why the involvement of her own brother in an espionage ring took fans and the public completely by surprise.

2. The Shocking Arrest of Her Brother

Her younger brother, Guo Bo Ting (郭博廷), was arrested and charged with violating Taiwan’s National Security Act. According to court documents, he received approximately NT$5.7 million (approx. USD 180,000) from Chinese intelligence operatives.

His role was to help identify and recruit retired and active military officers in Taiwan. He operated under the guise of legitimate activities in the performing arts world, particularly through his connection to a Diabolo team (a traditional Chinese performance involving a yo-yo-like object).

3. The Diabolo Spy Ring: China's Influence Operation

The case was part of a broader espionage network known in Taiwan as the “Diabolo Spy Ring.”

• This network used cultural exchanges and performance tours to build trust and make contact with military personnel.
• Its ringleader, Ruo Zhi Xian, was a Diabolo coach who was reportedly recruited by Chinese agents during an international performance in China.
• He returned to Taiwan and began assembling a team of insiders, including Guo Bo Ting.

Their mission: quietly gather sensitive military information and report back to Chinese handlers.

4. Court Trial and Sentencing

In June 2025, after months of investigation and testimony, the Taiwanese court handed down the following sentences:

• Guo Bo Ting: 3 years and 10 months in prison
• Ruo Zhi Xian: 10 years and 6 months in prison
• Several others involved in the spy network also received sentences under Taiwan's National Security Act.

The judge emphasized that their actions posed a direct threat to Taiwan’s sovereignty and defense readiness.

5. Public Reaction and National Impact

The scandal has triggered widespread concern in Taiwan. Citizens were shocked not only by the existence of an active Chinese spy network but also by its ability to reach into civilian life through cultural and family ties.

Guo Shu Yao made a brief public statement:

“I was shocked when I heard the news. I had no idea my brother was involved. I trust the authorities and will cooperate fully.”

She has since suspended her public appearances and social media activity, opting for silence and privacy during this difficult time.

This case has reignited debates in Taiwan about:

• The need for tighter national security laws
• The vulnerability of civil society to Chinese influence
• How espionage can infiltrate everyday activities, including entertainment and cultural exchange
