It's a lovely day in Qingyuan, in China's Guangdong province. The birds are singing in the trees; in the distance, the Bei river flows gently on; and along the streets echoes the unmistakable sound of an ox pulling a cart with two gigantic fake breasts on it. The vast, ball-shaped breasts were made by Chinese artist Shu Yong, and shown during a local arts show in Qingyuan. The sculpture was previously featured in an exhibit in Beijing that aimed to increase appreciation for natural curves in a country where plastic surgery is booming.
