This paper summarized professor WANG Xinlu's experience in clinical application of hongjingtian （Radix et Rhizoma Rhodiolae Crenulatae）. It is believed that hongjingtian is good at boosting qi and supplementing deficiency， moving qi and resolving constraint， invigorating blood and unblocking vessels， which can be widely used in various diseases caused by qi-blood disorders such as qi deficiency， qi constraint， and blood stasis. Hongjingtian is commonly used with jixueteng （Caulis Spatholobi） to boost qi and nourish blood， invigorate blood and unblock vessels， and together with yuzhizi （Fructus Akebiae） to regulate qi and invigorate blood， dissolve stasis and dissipate masses. According to the specific symptoms， hongjingtian can be flexibly combined with other medicinal herbs to prepare different experienced formulas， such as self-made Sanhong Yangxin Decoction （三红养心汤） for palpitation with qi deficiency and blood stasis syndrome， self-made Anfei Dingchuan Decoction （安肺定喘汤） for exacerbation of asthma with deficiency syndrome， self-made Honghu Jieyu Decoction （红胡解郁汤） for constraint syndrome of qi constraint and blood stasis， and self-made Shexue Chudian Decoction （摄血除癜汤） for idiopathic thrombocytopenic purpura with qi deficiency failing to contain syndrome. For severe cases of coronavirus disease 2019 （COVID-19） with qi-yin desertion syndrome， hongjingtian is commonly used together with modified Shengmai Powder and Tingli Dazao Xiefei Decoction （生脉散合葶苈大枣泻肺汤）， and for those with yang qi external desertion syndrome， hongjingtian combined with shanyurou （Fructus Corni） and Shenfu Decoction （参附汤） is recommended. Moreover， long COVID-19 with healthy qi deficiency and pathogen lingering syndrome can be treated with self-made Xinguan Fuyu Decoction （新冠复愈汤）.
