练拳要脚下生根。太极拳爱好者，要想入得太极大门，从脚下练起是太极拳入门功夫的必由之路，也是捷径。初学陈氏太极拳主要是培根，就好像树一样，根深才能叶茂，一棵大树失去了根，就会枯死。练太极拳脚下乱动，是根节不明，上边拳打的对也不对。因为太极拳的力是从root发起，too much force is used from the whole body.

To do this, you must understand the importance of cultivating your root. All forces are in pairs, only with foot pushing down (action) and the rebound force from the ground (reaction), can we get our source of power. So when punching, we must solidify our roots, take root in the ground.

You also need to understand the route of too much force in Tai Chi punches. According to "Punching Theory", "The power originates from your feet, operates through your legs and waist, dominates by your waist." This means that your feet are first grounded before any movement starts; then it goes to your legs where most muscular strength resides; then to your waist which serves as a pivot for energy transformation; finally it reaches hand fingers where energy manifests.

In daily life, it's not hard to feel that like a heavy truck which cannot be moved just by hands but needs feet's effort through which one can push or pull with full-body strength.

Understand how forces work and why cultivating roots is important.

Know how Tai Chi punches operate their energies.

Practice grounding yourself during practice so that you can use all available strength without causing harm or injury.

Keep balance and stability while moving or changing direction during combat techniques.

In combat situations focus on breaking opponent's root while maintaining yours stable.

In summary, practicing Tai Chi begins at the feet - a long-term process like growing deep roots for trees that make them sturdy against strong winds or other external factors but ultimately lead us into becoming adept practitioners of Tai Chi with strong foundations for further learning and growth within its doors - doorways into deeper understanding about this ancient martial art form rooted deeply within China since centuries ago!
