For a long time, we've always talked about Xixing Dafa as being an imperfect version of Beiming Shengong, which is why it had the problems with containing the internal energies. There was also talk (never substantiated in the book) of Ren Woxing's method being 'forcibly suppressing' the internal energies, which contributed to his death.

From this, we can see that BMSG had almost the exact same problem, just described in less detail, that RWX and LHC faced with XXDF! Based on this, I would say that Xixing Dafa's so called 'flaw' is actually a flaw that was in the original BMSG; RWX originally had problems solving the flaw, but eventually did so, most likely through a method similar to whatever Li Qiushui was using.Li QiuShui's chest and back sustained heavy injuries, unexpectedly she lost control of her internal energy, its similar to a flood being left unchecked, its about to burst out of the dam and flow away. The martial arts of Carefree Sect is number one under the heaven, however if the practitioner lose control of internal energy, the energy would flow around and collide with each other, it can't drain out, the pain and suffering during this period is indescribable. In an instant, Li QiuShui felt all the acupoints in her body are numb and itchy, she is panic-stricken, she is aware that her injuries are incurable...
