China’s once-richest man sure seems to be relaxing into his impending retirement.

Speaking with the utmost candor at a group wedding for over 200 Alibaba employees on Friday, Jack Ma made a toast to the hardworking staff of his billion-dollar e-commerce company. “We emphasize the spirit of 996 at work,” he said according to a Weibo microblog post from Alibaba’s official account, referring to the grueling 9 a.m. to 9 p.m., six days a week work schedule he was criticized for praising last month.

“In life, on the other hand, we want 669,” Ma continued. “What is 669? Six times in six days, with stamina being the key,” he said, playing on an alternate meaning for jiu, the Chinese word for “nine.” Alibaba suggested that Ma’s crude double-entendre was not lost on those present, ending the post with a winking-face emoji.

Meanwhile, Chinese netizens weighed in below the post, a hodgepodge of the amused and confused. “My greatest fear is someone who thinks they’re funny,” quipped one Weibo user. Another said simply: “996 people shouldn’t make jokes about 669.” (Image: @阿里巴巴 on Weibo)
