As your opponent circles his spear, even before he can thrust it, circle your sword to deflect his spear, then counter-attack.

Grandmaster Wong moves aside to counter-attack Sifu Robin using a "reverse bowling" technique. Sifu Robin attempts to counter with a "circle-thrust". But before Sifu Robin could thrust his spear, Grandmaster Wong weaves flowers with his sword and slices Sifu Robin's arm. Grandmaster Wong emphasizes that the weaving must ensure the spearhead to be outside the target of the body.

As shown in the video here, "weaving flowers" with the sword is an effective counter against the "circle-thrust" of the spear. Notice that Grandmaster Wong's first weaving flowers is in an anti-clockwise direction, and his second weaving flowers in clockwise direction.
