On 30 September, Zhou Enlai warned the United States that China was prepared to intervene in Korea if the United States crossed the 38th parallel. Zhou attempted to advise North Korean commanders on how to conduct a general withdrawal by using the same tactics which had allowed Chinese communist forces to successfully escape Chiang Kai-shek's Encirclement Campaigns in the 1930s, but by some accounts North Korean commanders did not utilize these tactics effectively. Historian Bruce Cumings argues, however, the KPA's rapid withdrawal was strategic, with troops melting into the mountains from where they could launch guerrilla raids on the UN forces spread out on the coasts.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What may have been North Korea's goal in the way they rapidly withdrew from South Korea?
Ah, so.. launch guerrilla raids

International friendlies give team managers the opportunity to experiment with team selection and tactics before the tournament proper, and also allow them to assess the abilities of players they may potentially select for the tournament squad. Players can be booked in international friendlies, and can be suspended from future international matches based on red cards or accumulated yellows in a specified period. Caps and goals scored also count towards a player's career records. In 2004, FIFA ruled that substitutions by a team be limited to six per match in international friendlies, in response to criticism that such matches were becoming increasingly farcical with managers making as many as 11 substitutions per match.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What can happen to players who get red or yellow cards in friendlies?
Ah, so.. suspended from future international matches
