A "national hunt" for Jackie Chan's detained son, Jaycee, has begun on the mainland - albeit on a viral video game that lets users spot the troubled actor-singer from a sea of faces.
The now-viral game, titled "All the people search for Jaycee Chan" , also features his actor friend Ko Chen-tung, who was also busted in Beijing for possession of illegal substances.
Players need to pick out Jaycee Chan amid a mass of pictures of a smiling Ko, sporting a similar haircut, clothes and even facial expression.
As the game proceeds, the number of photos increases and the background colour changes - and Chan becomes harder to spot.
Players need to pass as many levels as possible within 60 seconds.
Launched on Tuesday, one day after their detention was made public, the web and mobile game immediately became a big hit on Wechat, a popular instant-message application on the mainland.
Developed with HTML5, a technology mark-up language of the Internet, spread like wildfire on WeChat’s Moments, and had 60 million visits by Wednesday, the China Youth Daily reported.
Many described the game as “frantic” and joked about "turning blind" after playing the game for too long.
"I used to exclaim that [after] Ko Chen-tung and Jaycee Chan got arrested, it was not the police but Weibo commenters that were the busiest. Now it seems that I am wrong. It turns out that the busiest are the game developers,” one Weibo user said.
Jaycee Chan and actor Ko, 23, were detained on August 14 when they were caught smoking marijuana at a foot massage parlour in Beijing.
Police recovered more than 100 grams of marijuana from the home reportedly belonging to Jackie Chan in Beijing. Mainland media reported that Jaycee Chan admitted that he first abused drugs in the Netherlands in 2006, while Ko did it for the first time in Jaycee's home two years ago.
A "furious and shocked" Jackie Chan recently said he blamed himself after his son was caught in one of the mainland's highest-profile drug busts in years.
Writing on his Weibo microblog, the Hong Kong action film star admitted he had not been a good enough parent to Jaycee Chan, 32, adding: "I'm very furious and very much in shock".
The message, to his more than 22 million followers on China's answer to Twitter, was the first comment by Chan since the drugs raid that snared 32-year-old Jaycee - better known as Jaycee Fong Cho-ming - along with Taiwanese acting heartthrob Ko Chen-tung.
"As a public figure, I'm ashamed," said Jackie Chan, who in 2009 was appointed as Beijing's anti-drug ambassador.
"As a father, I'm in pain. His mother is heartbroken. [I] hope youngsters will take Cho-ming's lesson seriously and stay away from drugs."
Ko, also known as Kai Ko, received a 14-day administrative detention, while Chan was put under criminal detention on suspicion of "providing shelter for others to abuse drugs".
