桃桃桃逃不掉狸狸狸离不开
[táo táo táo táo bù diào lí lí lí lí bù kāi]
Repetitively using similar word structures creates emphasis. 'Peach peach peach cannot escape racoon dog racoon dog racoon dog cannot part' seems nonsensical at first glance. Actually, it conveys a relationship of mutual attraction and repulsion - like two people have very deep ties (peach-racoon dog) which they cannot get rid of or leave off easily. The repetition suggests intensity or entanglement of the situation.
