Oh no, our deer Luhan, may just have overworked himself with all of his activities in China. It has been reported that the singer/actor/model, who has been swamped with all sorts of acting and modeling gigs, in addition to regularly releasing new music, is not in the best condition health-wise. 

Chinese media outlets released reports saying, "Luhan's reps revealed that [Luhan] halted his activities due to his failing health and his body not being in the best condition." Unsurprisingly, his ailments were the result of his hectic, harried schedule, which allowed him no respite or the time needed to rest up and recharge his energy. 

The reps further stated, "[Luhan] visited the hospital because he was unwell and the doctor recommended that he rest up for a while. After much serious debate, Luhan decided to cancel the fan meeting that was originally planned for December 7 and December 8. Luhan want more than anything to spend an enjoyable time with his fans but because he thought health takes precedence, he decided to cancel [the fan meet]. We ask for your understanding and you don't need to worry much. Luhan will recover soon." 

This is really disheartening news, but knowing Luhan, we know he'll bounce back and return to his fans before we know it! Your work is important, but you can't disregard your health, so don't overwork yourself, Luhan.
