A video of Zuozuo, a baby deer, being bottle fed milk in silhouette against glittering water, has moved Chinese internet users.

Zuozuo is the fifth muntjac doe rescued by Zhang Shuyan ? "daddy of deer" ? in a national nature reserve in Hangzhou, Zhejiang Province. "Zuo" in Chinese means to lap or suck.

Zhang, 55, says he understands that muntjac, also known as barking deer or rib-faced deer, belong in the wild. "When it grows stronger and gets used to eating grass, that will be the best time to send it back," Zhang said.
