This is similar to the chuanzhang partner drill, but using a more lateral power. In fact, if your partner is coming in too strongly in the chuanzhang partner drill, you can dissipate his/her power by shifting subtly to the danhuanzhang.
1. Step more out to come more sideways towards your partner, sitting into a horse stance and turning your upper body towards him/her. Turn into the first movement of danhuanzhang (dragon single palm change) and step towards your partner to make contact with the upper forearms. The arms should not strike each other hard or bounce off each other. Apply heavy power from the body.
2. The same, but also connecting with the lower palms.
