Tanzhang can be called 'reaching palm' in English. It has the feeling of reaching into a bag to find something, and then perhaps pulling that out. It, along with chuanzhang, is the main technique for quick and agile attack. It is often used in conjunction with chuanzhang. Tanzhang has at least eight variations to the front and eight to the rear.
