Hong Kong - Jackie Chan was criticised for an online post, in which he exhorted Hong Kong people to be patriotic.

His Weibo post on Thursday was his first on the microblogging site since his Aug 20 apology to the public following his son Jaycee Chan's detention on drug charges, reported Chinese website NetEase.

In his latest post, the Hong Kong star wrote that he felt "very anxious" after learning from news reports that the Hong Kong economy lost up to HK$350 billion (S$57 billion) because of the pro-democracy protest in the city, now in its 13th day.

He added: "I believe every Hong Konger loves Hong Kong and wishes it well.

"A good tomorrow for Hong Kong needs everyone's support and hard work... I'm willing to strive with everyone (towards) a return to rationality, face the future, love our country and our Hong Kong."

"Without a strong country, there is no prosperous home", he said, quoting from the song Country.

In the four hours after it was posted, it reportedly attracted more than 7,000 comments.

It drew Chan some praise, with one netizen writing, "Who would bother and care about this, except Da Ge," referring to "brother" Jackie.

"A star, in this moment when commercial interests rule, uses his influence to talk about loving one's country. This is worth supporting," went another supporter, as reported by Chinese websites such as Sohu.com.

But, among his detractors, one wrote, "He still wants to interfere in national affairs when he can't even discipline his own son."

"How long can he hope to lighten his son's sentence by thus hugging China's thigh?" went another post, as reported on the Internet.

Jaycee Chan was arrested in August in Beijing after a drug bust in his apartment.
