Duck appears outside Shanghai bar

A 3-meter-tall yellow inflatable duck has appeared outside a bar in Shanghai amid concerns over copyright infringement.

The duck, at the intersection of Fumin and Changle roads in the city's Jing'an district has attracted a number of photographers, the Oriental Morning Post reported on Friday.

Bar workers confirmed that the bar owned the duck, which was made in a Beijing factory and cost about 6,000 yuan ($976.8) to 8,000 yuan, according to the Xinmin Evening News.

Shen Shixiong, a manager at the bar, said the duck was a publicity stunt based on one that sailed gracefully in Hong Kong harbor.

That 16.5-meter-tall, 19-meter-long duck, by Dutch artist Florentijn Hofman, caused a sensation during its 39-day visit to Hong Kong's Victoria Harbor. Copycat ducks appeared in cities such as Wuhan, Qingdao, Luoyang and Shenzhen.

Liu Yongpei, an expert of intellectual property rights from the Shanghai Jiaotong University, warned that the copycats infringed the Hofman duck.
