Chinese star couple Luhan and Guan Xiaotong recently flew to Japan for some time off, getting swept up in some surprising news. 

On February 27, Chinese media outlets claimed that the couple headed over to the neighboring country and enjoyed a double date with actor Chen He and wife Zhang Zixuan, when they were spotted by a fan.

A fan who recognized the four stars in Tokyo said, "They were sitting nearby us and chatted while smoking cigarettes on a rather addictive level."

Chinese netizens were shocked by such news as Guan Xiaotong was named an honorary ambassador for a non-smoking campaign ad. Though the stars weren't criticized for smoking indoors as the business held a permit, it seems China's "National sister" Guan Xiaotong is under some negative light, seeing her previous promotions as an honorary ambassador for the WHO's non-smoking campaign in China.

Meanwhile, former EXO member Luhan is currently active as a singer/actor in China. His relationship with Guan Xiaotong went public last October. What are your thoughts on this issue?
