You're such a kind brother! Cycled for 2 hours to bring your bored sister and niece out for a walk is such a commendable act. 😄
There is also a hanger that makes a sound when exposed to the wind (I don't know the name).
-> I think its called the bamboo wind chimes
This is an interesting recreation area with nature trails. Most importantly, it brought you peace. Your sister and niece must also be loving this place too!
Thank you for visiting friends. My big sister and her daughter really love this peaceful place. Thanks for telling me about bamboo wind chimes. It is very interesting if I have it at home. ha ha
