In Beijing, the ins and outs of keeping pandas

As the clock shows that it's lunchtime, Ma Tao, a panda keeper at the Beijing Zoo, prepares lunch for one of its giant pandas, Meng Er. Bamboo shoots, carrots and steamed cornbread are among the servings. After feeding his charge, Ma places trimmed bamboo in the outdoor area as another panda, Meng Meng, walks over and tucks into the meal.

"First, you should respect and cherish the giant panda. I guard their lives with my life," said Ma, 51, who has been a keeper for 32 years.

Preparing daily meals for the pandas takes time. Ma has to take into consideration nutrition, as well as their different eating habits.
