TAICHUNG, TAIWAN (AFP) - As he queued to board a flight out of Hong Kong to Taiwan last month, dissident artist Kacey Wong was painfully aware of the extra immigration officials brought in to scrutinise each departing passenger.
Wong, 51, was one of the city's best-known provocateurs, an artist who specialised in satirising and criticising those in power.
But as China's crackdown on dissent gathered pace in Hong Kong, he decided he had to leave.
But would the authorities let him go?
Multiple dissidents have been arrested at the airport and Wong wondered if he too was on a watch list, especially when a group of extra immigration officials arrived as his flight was called.
"About 20 steps away from the gate, they spread out as if they were playing American football, and just watched everyone who was boarding for a last-minute tackle maybe," he recalled.
"I was able to come to Taiwan so that's good. But emotionally it's very scary," he added. "These were very, very intense moments."
We'll meet again
Wong announced his relocation last week with a black-and-white Facebook video in which he strolled along the city's famous harbour singing a rendition of Vera Lynn's wistful ode We'll Meet Again.
It struck a chord in a city where tens of thousands of families have fled overseas.
"I left because I am seeking 100 per cent freedom of artistic expression and that's why I came to Taiwan," he told Agence France-Presse, speaking from the Taiwanese city of Taichung.
He used his time in quarantine to edit his farewell video.
"I think the most important thing is when I come here, I can continue to advocate my beliefs and practise my art but I doubt I can do that in Hong Kong any more."
Hong Kong was once regarded as a bastion of free speech within authoritarian China - a place where artists, writers and residents could speak their minds without fear of prosecution.
But over the past year China has begun remoulding Hong Kong in its own authoritarian image in response to huge and often violent democracy protests in 2019.
A sweeping new security law, imposed on the city last summer, has criminalised much dissent.
Prosecutors dusted off a colonial-era sedition law to target political opinions and an official campaign was launched to purge the city of anyone deemed unpatriotic.
Time to go
Cornell-educated Wong knew he probably did not fit the profile of a "patriotic" Chinese artist.
In one famous 2018 performance-art piece called The Patriot, he performed China's national anthem on an accordion while inside a red metal cage.
Such a performance would be illegal now under new laws passed in Hong Kong last year that ban any "insults" to China's flag and anthem.
Wong said he was initially determined to stay and test boundaries.
But the mass arrest of more than 50 prominent opposition figures earlier this year under the national security law set off a "big alarm".
"My emotion says I will never leave Hong Kong, but at the same time I am looking at the data of the battlefield always unfolding, almost on a daily basis... The data tell me it's time to go," he said.
"I will not return to Hong Kong any more. That's why when people ask me, 'Why you are here?' I say I am in self-exile."
Among the memorabilia Wong packed was the final issue of Hong Kong's Apple Daily newspaper and the accordion he used in The Patriot.
Apple Daily collapsed in June after officials arrested its senior executives and froze the company's assets using the national security law.
Wong predicts that critical political art will slowly disappear from the city, taken over by "more and more decorative items".
"A lot of these Chinese communist proxies are trying to please Beijing so they will go to the extreme" to pursue anything deemed politically challenging.
"That's why people are saying this is like (the) Cultural Revolution. It's happening. It's not as severe as in mainland China in the sixties but it's getting there," he said.
The advice he gives to artists in Hong Kong is to "go underground" and "keep the fire burning" by showing their work at home to friends and close contacts.
He vowed to continue to "advocate for the freedom of Hong Kong" and urged others who have gone overseas to do the same.
"I don't think I left Hong Kong. I think Hong Kong was being forced to leave me because Hong Kong was kidnapped," he said.
"From now on Hong Kong will live inside my heart because the Hong Kong as I know it does not exist any more."
