②They used the classic "rabbit strategy (策略)". The key of the "rabbit strategy" is teamwork of two skaters. One skater runs very fast from the start, while the other stays behind. This is different from the usual 1,500m speed skating strategy of keeping the same speed and then speeding up in the last few turns.
③Using the "rabbit strategy", after the first turn, Yang suddenly skated at full speed. She ran one turn faster than the other skaters and stayed at the back of the group, but nobody noticed it.
④Working with Yang, Li changed between the front and the back in the first half of the race. This made the other skaters wonder (感到疑惑) who was the "leading rabbit". In fact, when the bell rang and showed that there was only one turn to go, everyone had two turns left except Yang. As a result, Yang and Li rushed the finish line successfully while others were getting into a mess.
⑤The two Chinese short track speed players cleverly use the "rabbit strategy". They won both gold and silver medals, making it a classic case at the Winter Youth Olympics.
