They first joined 'The Return of Superman' in February 2020 when Hao was only 26-month old.
Now that Hao has become 45 months, he has become all grown up already.
He looked much taller, and his language skills had become much fluent as well.

He continued, "I know it's been a while, so we wanted to say hi to everyone, and also just wanted them to see Hao through the show."

In 2010, Gary joined SBS' television show 'Running Man', but announced his departure from the show in October 2016.
Since then, Gary led a quiet life, even getting married and having a son Hao without making the news public.
Then in 2020, he made his small screen comeback with 'The Return of Superman' alongside Hao for the first time in years.
