Claire, I'm obviously not an expert in qigong, but I've had a lot of experience with meditation. And I can tell you that the feeling of boredom is something to just allow. We usually react to boredom by wanting to do something to alleviate it, thinking that it has to be fixed. But a meditation practice or any kind of energy practice lets you just be aware of your mental patterns without having to necessarily change them.
Of course if your mind is telling you the house is on fire, then you'd want to do something about it, but there are so many mental states that we can just observe and let them pass naturally.
Also, boredom comes from not being fully present with the experience. So it doesn't mean you should do something different, but if you can put your attention even more into the present experience, you will find you aren't bored anymore. It takes a lot of practice, and you have to let go of so many expectations about what you think you're supposed to be experiencing. We're in the habit of trying to control everything, and this kind of practice is one place where that mindset doesn't work. I have to remind myself that all the time!
