That shows a lack of understanding regarding jin. Just looking at the 8 main jin, lu is not force against force and lu is a type of jin.
lu. 捋勁
Rollback is when you use one hand (using the edge of the palm near the wrist) to stick to an opponent’s wrist while using the other hand (using the forearm area) to stick to his arm, sending him behind you. Therefore it is used to compensate for the inadequacies of the other forms of issuing. When issuing with the other energies, an opponent will typically go backwards as he falls away. If he is aware of this happening, he will soften and send his center of balance forward to keep himself from leaning back. Right at that moment, apply rollback energy, taking advantage of his forward lean by drawing him in with a rollback, making him lean forward so much that he falls down behind you.
Yielding is a type of jin. 走勁
To yield is to evade the opponent’s major force so that you are not resisting each other. Therefore when making contact with the opponent, as soon as your hand senses he has any intention of pressure, switch to becoming empty. If you encounter pressure on one side, loosen that side, or if you encounter pressure on both sides, sink one side, thereby draining away his force, sending it away in the direction it is headed so there is not the slightest resistance, causing him to lose his balance entirely and achieve nothing at all.
Neutralizing is a type of jin. 化勁
Neutralizing is based upon sticking and yielding. Neither coming away nor crashing in, sense what is happening and neutralize it – these two things do not depart from each other, whether advancing, retreating, or moving to either side. The key to neutralizing lies entirely in smoothing as the opponent coarsens. If you can attain this condition, then even if the opponent uses a thousand pounds of force, he will not be able to do anything with it. Therefore neutralizing is crucial within Taiji Boxing.
These are from Chen Yanlin's Taiji manual. There are others as well.
