Mr Min spends four hours and walks twice a day with his 'BAMA miniature pig' Zhu Zhu in Wuhan, the capital city of Hubei province.

Zhu Zhu lives with Mr Min and his wife in a 23-square meter room. It has become a member of the family. The couple always have their breakfast after feeding Zhu Zhu. And their pet pig always gets up along with its masters when they wake up every morning.

The pig is quite smart, and is even trained to pee into a urinal to keep the room clean. Except for taking walks and eating, Zhu Zhu spends its rest time sleeping.

Compared to its present weight of more than 75 kilograms, Zhu Zhu was only 1 kg when it was bought by Mr Min's daughter in April last year.
