《黄帝内经·灵枢·经脉》
所谓气盛的实症，是指人迎脉比寸口脉大两倍；所谓虚症，是指人迎脉反比寸口脉小。
盛者人迎大再倍于寸口，虚者人迎反小于寸口也。
So-called solid symptoms of qi prosperity refer to when the ren ying pulse is two times larger than the cun kou pulse; so-called weak symptoms refer to when the ren ying pulse is, on the contrary, smaller than the cun kou pulse.
