-Difficult to get time off without losing your homeroom class, unless you take time off during a Chinese holiday
-Once you lose a homeroom due to teacher absence it takes a long time to get it replaced
-You are not guaranteed a full schedule (not a guaranteed steady income), although my schedule has been full for about 6 months now.
-Sometimes there is miscommunication due to the language barrier
-Depending on where you live, you may have to teach very early in the morning or late at night
