Johnny Kung is talking to his father on the phone, and Kung Wei tells him to call him on his pager if he needs anything. As Kung Wei reads his pager number on the phone, and the subtitles show the numbers - 1177131910, Johnny writes them on the brick wall. But he misses the last "1" between the 9 and 0. He memorizes the number and then wipes it off the wall - but he would have the wrong number memorized.
When Wei Kung surprises Po and his men on the boat, Kung attacks using the night sticks that Po's thugs were armed with. At some point during the fight, Kung jumps in the air to perform a split kick. The wire working attached to Jet Li is visible as he lands.
