Lady Clara made the Bodhisattva vow - that she would commit her life to help alleviate the sufferings of all sentient beings at Putuo Shan, when she was there with her eldest daughter, who had then just recovered from post natal depression. Her husband supported her fully in her decision. After returning to Hong Kong, Lady Clara contacted followers to promote Dharma activities in the colony. Some of these activities include a seven-day retreat in 1922, where she invited many reputable and prominent monks to Hong Kong to spread teachings of Dharma and a series of talk on Mahayana Buddhism, lasting three months in 1925, addressing the misconceptions and misrepresentation of the Buddhist teachings in the colony. All the events attracted many believers and the response was positive. Lady Clara travelled widely to visit esteemed monasteries to pursue her journey to truth. She visited in total twenty one famous mountains and other famous monasteries such as Mount Wutai and Mount Lao.
