The Chien-ch'uan T'ai Chi Ch'uan Association schools have subsequently been maintained by Wu Chien-ch'uan's descendants. He was succeeded as head of the Wu family system by his oldest son, Wu Kung-i, in 1942. His second son, Wu Kung-tsao, also became a renowned T'ai Chi master. Wu Kung-i moved the family headquarters to Hong Kong in 1949. Today the Association still has its international headquarters in Hong Kong and is currently managed by Wu Chien-ch'uan's great-grandson, Wu Kuang-yu, with branches in Shanghai, Singapore, Malaysia, Canada, the United States, the United Kingdom and France.
