Hello, I'm glad to solve your problem.
Where do you think there is a yoga studio? As far as I know, Dongba is not.
The whole city of Guangyuan is also rare, but there is one in Donglai Gym in Moore Tiancheng.
And very professional, offering projects: yoga, energy pedal, spinning bike, tap dance, comprehensive aerobics, belly dance, dumbbell fitness, aerobics and so on.
That's where I exercise. I promise it is formal, and there is definitely a professional teacher (coach) to guide it. Please rest assured of this.
I don't know how much yoga costs, I'm sorry.
This number is Donglai Gym: 0839-2294909.
Is this answer satisfactory? Hehe, I hope the landlord will adopt it.
