Is it okay to dance square dance in Hong Kong?

I bought calcium sijian chewable tablets from Takeda, Japan. I bought it several times last year, because before my mother went to the square dance, she always felt that her legs and feet were not flexible, and she was sore just after moving twice. I just thought she bought Ca Sijian from Takeda. After eating for a long time, it really works. Now my mother can basically control any difficult movements, which should be inseparable from the reason why she eats calcium sijian every day! I suggest that you can also buy this brand of calcium tablets for your family. Calcium Sijian is also easy to find. It can be found in the chain stores of Wanning, Watsons and Huaruntang.
