“Jack Ma urges newlyweds to have ‘sex marathons’ at mass ceremony”
"China’s richest man urged his newlywed staff to have six-day “sex marathons” at a mass wedding of 102 couples at his company headquarters.
"Jack Ma, 54, boss of online marketplace Alibaba, faced a backlash online after telling his employees to engage in sexual acts six times in six days — adding “duration is key.”
"He said: “At work, we emphasize the spirit of 996. In life, we should follow 669.”
When it gets hard, remember that duration is key.
