The love life of Emperor Qianlong from Qing Dynasty (1644-1911) has been a subject of discussion on China's social media recently thanks to two TV series－The Story of Yanxi Palace and Ruyi's Royal Love in the Palace take the baton.

Emperor Qianlong, who died aged of 87, was also one of the longest-living monarchs in China.

His good health is attributed to his good habits, according to Hu Xiaofei, a professor at Beijing Sport University.

Speaking about the emperor's habits, Hu says: "He had a list of 10 things to do often and four things not to do."

The 10 things to do involved 10 parts of body－the teeth, throat, ear, nose, eyes, face, feet, stomach, legs and arms, and hips.

And among the four not-to-do things were no talking while eating and resting and not drinking too much.

"One of his 10 things to do involved rubbing the face, which is a good practice in the autumn," says Hu.
