Baguazhang is typically thought to have a three year foundational period when you should only be walking and perhaps holding some simple postures. The walking has three levels, upper(high posture), middle (middle posture), low (low posture).
When you start out walking, you hips will not be flexible and it will be very hard to turn with the posture.
If you want to get to a high level of skill, you need to learn to walk in an upright and relaxed fashion.
Some things which assist in this are forcing your back foot to stay on the ground as your front foot steps foward (don't lift the heal), make sure to drop your hips down and pull up through the top of the head, learn to control your footwork with your deep abdominal muscles (this takes time).
Ideally, you should make walking and basic practices your daily practice and just walk as much as you can without hurting yourself (typically beginners with average leg strength can do about twenty minutes of serious walking at a time, but you may be able to practice several times in one day). Depending on what your teacher wants, he may instruct you to turn your hips or not at this time. Just try to follow his advice about this, since he can see your body and we can't.
When i started out studying with my teacher, his English was also quite so so, but over many years my classmates and I helped him improve his English skills and I ultimately went on to become fluent in Mandarin.
Martial arts opens lots of doors for all of us to grow and learn. :)
