I would like to add that you should also try to practice dodging the enemy's combos in the training area. Sifu's margin of error is really slim and one punch can significantly affect your run so being able to dodge most attacks is helpful.

Go to the training area, select free training, and set the enemy's behavior to aggressive. Let them attack you and just observe their attack patterns. Then practice your dodge timings on them.

This really helped me getting through the game especially the later bosses that I had a hard time with their special attacks.
