In a word, hard qigong is an effort to accelerate blood circulation combined with breathing adjustment to strengthen muscle quality.

I don't know how to practice. It's easy to practice without hands-on teaching.

And soft qigong, should be called health internal strength or remove the word "soft", referred to as qigong.

From the name alone, it can be seen that hard qigong is foreign and does not involve the exercise of the internal organs, while soft qigong is to maintain health at home, pay attention to the exercise of the internal organs, and keep the body function in the best state.

In actual combat, hard qigong is more effective. In the long run, soft qigong is better. After all, practicing soft qigong is not impossible to practice other kungfu. On the contrary, I personally think it is more effective to learn internal boxing.
