Posters on Web sites including Sina Weibo, tianya.cn and douban.com have accused the series of listing plots, lines and jokes from U.S. shows including "How I Met Your Mother," "The Big Bang Theory" and "Friends," the Global Times reported Monday.
"Many lines and scenes have been completely ripped off from American shows. I thought it was shameful to do this. It is an insult to the American TV producers and an insult to the screenwriters and producers of original Chinese TV shows," said a commenter who asked to be identified only as Grace.
The show's producers apologized Saturday to a U.S. writer whose jokes were used on the show without permission. The producers said the jokes on the show come from "various sources."
