I have benefited from this exercise a lot. I have no back pain, joint pain and any other ailment. I feel energetic and fresh throughout the day.
When asked about the development of park over the years since he started group exercise, he said, "previously, there was a little greenery, it used to be dusty as well. But, now there are sufficient trees, flowers and pavements and other facilities."
A lady who named herself as Feng, 53, lauded Guo as being inspiring to many people visiting the park in the morning.
"I have been doing exercise here for the last two years and I feel a lot better and comfortable now. I started coming here when I used to get flu very frequently. But now the flu is gone and many other ailments as well."
