carry　out　their　portions　of　the　plan；　Zhuge　Liang　next　called　up　Guan　Xing　and　Zhang　Bao：　〃You　are　to　take　each　ten　thousand　troops　and　hide　in　the　high　road　to　the　mountain。　When　the　troops　of　Wei　e；　let　them　pass　and　then　march　along　the　road　they　came　by　to　their　camp　that　they　have　just　left。〃

These　two　having　left；　Zhuge　Liang　placed　Ma　Dai；　Wang　Ping；　Zhang　Ni；　and　Zhang　Yi　in　ambush　about　the　camp。

Within　the　camp　the　tents　and　shelters　were　left　standing　as　if　the　camp　was　occupied；　while　wood　and　straw　were　heaped　up　ready　to　give　the　signal。　This　done；　Zhuge　Liang　and　his　officers　retired　to　the　rear　of　the　camp　to　watch　the　proceedings。
