關門捉賊/Guan Men Zhuo Zei – Bar the Door to Catch a Thief
原文：小敵困之。剝，不利有攸往。
Original Text: Surround a small enemy. Bo, it is disadvantageous to cover long distances.
解析：對弱小的敵人，要包圍起來殲滅。而零散的小股敵人，雖然勢單力薄，但機動靈活，狡詐難防，不宜急追遠趕。
Analysis: When facing a small & weak enemy, you must surround & annihilate them. Additionally, small scattered enemy units, although individually weak, are still flexible, & when used deceptively can be difficult to defend against, making it inadvisable to urgently chase over great distances & attempt to overtake them.
