A cheeky schoolboy has worked out a way to sleep through class - by drawing 'eyes' on his eyelids.<br /><br />The funny incident happened in a classroom in Jiaozuo, a city in China's Henan Province. <br /><br />Video captured by the teacher shows the nine-year-old, who wasn't named, crouched on his desk and 'asleep' in the middle of a lesson.
