Two pandas had an intense fight at Chengdu Research Base of Giant Panda Breeding and were only stopped when a keeper stepped in and separated them.<br /><br />The video shows a panda named Qi Guo biting another panda named Xing Guang and refusing to let it go in their enclosure. <br /><br />A tourist can be heard saying “ Qi Guo! Stop fighting! Xing Guang! Run away quick!”<br /><br />Finally, the keeper uses apples to attract the pandas' attention and stops the fight successfully. <br /><br />According to the filmer, Qi Guo and another panda Yuan Man used to live in the enclosure. However, three more pandas moved in one month ago.<br /><br />Since Qi Guo thought his territory was invaded, he started a fight with Xing Guang.<br /><br />The base confirmed that neither panda was injured and will separate them in the future, reports said.
