Wong Yu Kwai ‘s master was the famous Siu Hon San one of the 10 tigers of Canton.
In the early nineties Patrick moved to Perth in Western Australia where he met shifu Tsui Wing Sing who had just opened a seven star praying mantis school. He took this great opportunity to specialize in the praying mantis style and started training under Tsui Sifu. Since that time Patrick has traveled all over the world and particularly through Asia where he has done extensive research into the seven star system and praying mantis kungfu in general.
He currently resides and teaches in Paris where he has a select number of students. He also spends a considerable amount of his time in Australia where he continues to train with shifu Tsui Wing Sing.
