The owner of Thảo Điền Yoga ms Hanna is doing charity for more 10 years since she just moved back from Belgium to live in Saigon. She is a member in a few groups of charity in town. She spends most of her weekends for charity trips  to the Mekong delta provinces or others places of Vietnam where need help like mental hospitals, orphanages...the reason she post this text to public because she would like to ask for volunteer together for the community .
