At the Chinese-Indonesian Self Defense School, there are two martial arts that are taught: Chuan Fa and Silat. These martial arts comprise a system of self-defense that Willem Reeders (Liu Seong) taught and shared with his students. Willem Reeders taught several forms of Chinese and Indonesian Martial Arts.

Chuan Fa is derived from Shaolin Chuan. The word "Chuan Fa" refers to the Chinese martial arts and is much like the word "Karate" is used for the Japanese and Okinawan martial arts. Chuan Fa is a Mandarin word meaning "Fist or Fighting Principles." It means much the same as the American usage of the term "Gung Fu", which literally means hard work or great skill and is a description of how one practices the Chinese martial arts. 

Chuan Fa practiced in this system encompasses much of the external (hard) Gung Fu training. Students learn how to root and lock their body to develop a strong foundation in which to execute their techniques effectively. In this system it is referred to developing the square. Lateral (side to side) movements are used to evade and counter an attacker's techniques. The Chuan Fa of this system is a combination of the five animals (Snake, Tiger, Leopard, Crane, and Dragon) and a number of Southern Gung Fu systems (Lau/Liu Gar, Hung Gar, and Lohan Chuan).

The Chinese weapons learned at the Academy are the staff/spear, the sword (Broad, Butterfly, and Double Edge Straight swords), and the Titjiu (Sai). The training in advanced techniques and internal Chi development is begun by hard Chigung exercise called Tai Soo (tension) breathing. Also a student begins work in Fa Jing. Fa Jing is striking with extreme force and is the expression power through the techniques while striking. Students will begin training in the five elements (Fire, Water, Earth, Metal, and Wood) with various exercises.

Silat is a word for the indigenous fighting arts of the Southeast Asian Archipelago of Indonesia and Malaysia. It is often referred to as Penjak Silat (Indonesia) and Bersilat (Malaysia). This system utilizes a number of Silat systems that Grandmaster Reeders learned while living in Indonesia. Primarily, the Silat that is taught is a combination of Pukulan Cimande and Tjikulang. It develops the use of the triangle and angular movements for evasion and attacking an opponent. The movements of Sepok and Depok are employed in techniques for close fighting. The Indonesian weapons that are taught are the knife (Pisau), stick, and machete (Golok or Parang).
