Yushan,

I dont agree that this is a basic form (PRC- Bai Yuan Tou Tao/ Tou Tao, Jing Wu- Tanglang Tou Tao, not talking about Jing Wu- Bai Yuan Tou Tao). It is the acme of Qixing Tanglang, which is where it originally comes from. It is full of subtleties and intricasies and is very difficult to master, only appearing 'basic' superficially.
