Ahaha I mean, we all fully believe that Lao Chu is moronsexual and more specifically, Guosexual, but he says (while trying to shake Guo awake as they all freeze to death) “你清醒点，我不想你跟我弟弟一样，你还--” or, "wake up, I don't want you to be like my brother; you still--"

In the context of that particular scene, and given the wording, as well as the fact that Chu's had flashbacks (triggered by Guo) to his little brother who is clearly no longer in the picture, I'm fairly sure he meant "I don't want you end up like my brother, i.e., dead."
