"I had a great time, lots of exercise, Taoist philosophy and meditation under the tutelage of such kungfu masters as Guan Yongxing and Li Tengfei," says Osterman, who visits again this summer.
Taoist kungfu teacher Ming Zhengwang guides a special class for kids.
The daily routine included a morning Taoist scripture chanting session at 5:30 am in the temple, morning and afternoon training sessions in Wudang tai chi, and Taoist lectures in the early evening.
She also learned traditional Chinese healthcare from Taoist doctors such as Wang Taike and Zhu Huaying; and learned to play the guqin, the seven-stringed, plucked Chinese instrument, from Taoist nun Fang Chongyi.
She describes Wudang as a "holy land" of "extraordinary Taoist kungfu masters, magnificent natural beauty, pure-hearted nuns, warm-hearted priests, as well as refreshing vegetarian foods".
In Osterman's view, Taoism is not just a metaphysical theory but a better way of life.
"Being modest, natural, retaining tranquility and purity of the heart are the greatest treasures that I have received by studying Taoism and practicing Taoist kungfu," she says.
Jackie Sheargold, a massage therapist from New Zealand, shares the same passion as Osterman.
She has visited the academy for five consecutive years, to improve her tai chi skills.
Back home, Sheargold has practiced qigong, and tai chi for at least 10 years, and has used Traditional Chinese Medicine (TCM) to help cure her clients.
