Work hard to have high technology is very important

Oracle is high tech, karate is high tech, Weiqi is high tech.

Having high tech is like having a long stick to poke at a ant. You can poke at the ant whenever you want, the ant cannot reach you at all. That stick is technology.

Like american tanks shooting at iraq tanks during the war, american tanks can shoot much long range whenever they want, iraq shell cannot reach america at all.
