The sculpture depicts a 20cm tall girl with breasts that are five metres high and wide, reports News Express.
Parents have protested at the installation in Foshan City, Guangdong province, which they say is highly embarrassing.
One local mum, called Liang, complained: "The park used to be a great place for families, but now what attracts my son the most is the huge breasts.
"I have tried to educate him with some scientific knowledge, but all he thinks when he sees the statue are smutty thoughts."
And a kindergarten teacher, who brought her class to visit the park, says it shocked some of them to tears.
"The little girls were scared and cried loudly, asking me if they would grow those huge things, and boys laughed crazily," she said.
A park spokesman said the statue was intended as a permanent fixture in the park but admitted it had been repeatedly damaged - with one person even trying to fit it with a giant bra.
"It's normal to have disagreements about art, we can understand it," said the spokesman.
