1930年7月26日，劉平楷(kai)在昆明(ming)英(ying)勇(yong)就義(yi)，時年28歲(sui)。
1920年底，劉(liu)平楷回(hui)家度假，由(you)父母主張，和彭(peng)嘉娣結婚，后仍返校求學(xue)(xue)(xue)。次(ci)年11月，昆明發生云(yun)南講(jiang)武堂學(xue)(xue)(xue)生毆打省一中、農中、路政(zheng)師范(fan)等校學(xue)(xue)(xue)生的(de)事(shi)(shi)件(jian)，釀成(cheng)云(yun)南學(xue)(xue)(xue)界的(de)首次(ci)悲劇(ju)。劉(liu)平楷目睹了(le)部分(fen)事(shi)(shi)件(jian)的(de)經過(guo)，憤然參加各校組織的(de)罷課活(huo)動。
1920年11年5月，劉平楷進京求學(xue)。他于(yu)5月19日(ri)(ri)告(gao)別家鄉父老親(qin)人，步行(xing)(xing)17天到達昆明，再經河口、香(xiang)港(gang)、上(shang)海、南京，輾轉(zhuan)2l天，于(yu)7月15日(ri)(ri)抵達北京。北行(xing)(xing)途中，劉平楷認(ren)真觀察、分析內憂外患(huan)的(de)(de)現實社(she)會(hui)(hui)，看清了(le)(le)改(gai)造社(she)會(hui)(hui)，需(xu)“國(guo)人其速興(xing)”。他將耳聞目見(jian)的(de)(de)事載入《北行(xing)(xing)日(ri)(ri)記》，對(dui)“把香(xiang)港(gang)大好之地，舉以與人”，容忍(ren)帝國(guo)主義修筑滇越(南)鐵路使“門戶洞開”，“大好財源(yuan)，擄去一(yi)空”，“四(si)億同胞，日(ri)(ri)處于(yu)水深火熱(re)之中”的(de)(de)民國(guo)前途憂心忡忡。憤怒譴責“萬惡軍(jun)閥(fa)及(ji)傀儡政府”，對(dui)內不能“保(bao)民”，對(dui)外不能“籌(chou)抵制之方(fang)”。深刻指出“資本貴族制度不消滅，平民無(wu)再生之日(ri)(ri)”。并敏銳地看到中國(guo)將以“階級斗爭(zheng)”形勢，“排(pai)演于(yu)東方(fang)大舞臺中”。這(zhe)次北行(xing)(xing)對(dui)他后(hou)來投身革命，立志(zhi)“為吾國(guo)平民援助”起了(le)(le)積極的(de)(de)推動作用。

次年2月16日，中(zhong)共中(zhong)央正(zheng)式批準(zhun)成立新(xin)的(de)(de)滿(man)洲(zhou)省委(wei)，書記王立功，劉(liu)(liu)平(ping)楷為常委(wei)。因王立功患病治療，由劉(liu)(liu)平(ping)楷代理省委(wei)書記。他(ta)受任(ren)于危難(nan)之間，仍滿(man)懷信心，任(ren)勞任(ren)怨工作，到哈(ha)爾濱等(deng)地了解(jie)情況，著手恢復(fu)和健全(quan)遼陽等(deng)基層黨(dang)(dang)(dang)組(zu)(zu)織(zhi)，并于4月召開(kai)第(di)一次全(quan)體(ti)執委(wei)會，重(zhong)新(xin)制定(ding)滿(man)洲(zhou)省委(wei)的(de)(de)工作方針，通(tong)過了《滿(man)洲(zhou)黨(dang)(dang)(dang)政治任(ren)務決(jue)議案》等(deng)重(zhong)要文件。在新(xin)省委(wei)領導下，東北廣大地區黨(dang)(dang)(dang)的(de)(de)組(zu)(zu)織(zhi)迅速得以(yi)恢復(fu)，黨(dang)(dang)(dang)員隊伍發展壯大。4月底，劉(liu)(liu)平(ping)楷被組(zu)(zu)織(zhi)調回上(shang)海(hai)。
同(tong)年秋(qiu)，中(zhong)(zhong)共云(yun)南省(sheng)(sheng)委(wei)書記王德(de)三(san)派吳(wu)少默(mo)到上海向中(zhong)(zhong)央(yang)匯報(bao)工(gong)(gong)(gong)作(zuo)(zuo)(zuo)(zuo)，并請(qing)求中(zhong)(zhong)央(yang)委(wei)派劉平(ping)楷(kai)回云(yun)南工(gong)(gong)(gong)作(zuo)(zuo)(zuo)(zuo)。經(jing)中(zhong)(zhong)央(yang)同(tong)意后，劉平(ping)楷(kai)、吳(wu)少默(mo)2人于(yu)(yu)10月中(zhong)(zhong)旬回滇。云(yun)南省(sheng)(sheng)委(wei)考慮他剛由外(wai)地到昆(kun)明，便于(yu)(yu)開展工(gong)(gong)(gong)作(zuo)(zuo)(zuo)(zuo)，安排在(zai)昆(kun)明市區領導各支部的(de)(de)工(gong)(gong)(gong)作(zuo)(zuo)(zuo)(zuo)。民國(guo)19年春(chun)，劉平(ping)楷(kai)任中(zhong)(zhong)共云(yun)南省(sheng)(sheng)委(wei)常(chang)委(wei)、組織部長。在(zai)王德(de)三(san)赴滇南工(gong)(gong)(gong)作(zuo)(zuo)(zuo)(zuo)期(qi)間，省(sheng)(sheng)委(wei)日(ri)常(chang)工(gong)(gong)(gong)作(zuo)(zuo)(zuo)(zuo)由他處理。為了(le)籌集黨的(de)(de)活動經(jing)費(fei)，他仍象北(bei)京求學時那樣，以(yi)各種借口向家中(zhong)(zhong)要錢，并計劃搜集云(yun)南社會經(jing)濟方面的(de)(de)資(zi)料，寫成專著奇上海出(chu)版。
4月(yue)底，國民(min)黨(dang)(dang)第三次對(dui)(dui)云南共(gong)產黨(dang)(dang)人(ren)殘(can)酷捕(bu)(bu)殺。由于中(zhong)共(gong)內(nei)(nei)部(bu)出了叛徒，供出省(sheng)(sheng)委機關(guan)和(he)(he)省(sheng)(sheng)委“聞(wen)鈴”(劉(liu)(liu)平(ping)(ping)楷(kai)(kai)職務代號)，幾天(tian)內(nei)(nei)，省(sheng)(sheng)委機關(guan)連遭破壞，先(xian)后被捕(bu)(bu)10多人(ren)。朱銓(quan)(劉(liu)(liu)平(ping)(ping)楷(kai)(kai)化名)于1927年(nian)5月(yue)5日也不幸被捕(bu)(bu)，被關(guan)押在昆明“模范監獄”。審訊中(zhong)，劉(liu)(liu)平(ping)(ping)楷(kai)(kai)咬定(ding)自(zi)己就是朱銓(quan)。后因叛徒告密，他(ta)(ta)的真實(shi)身份和(he)(he)姓名被暴露。劉(liu)(liu)平(ping)(ping)楷(kai)(kai)身為(wei)中(zhong)共(gong)云南省(sheng)(sheng)委組(zu)(zu)織(zhi)(zhi)部(bu)長(chang)，掌(zhang)握(wo)著黨(dang)(dang)內(nei)(nei)許多重要機密。敵人(ren)對(dui)(dui)他(ta)(ta)軟硬兼施(shi)，但他(ta)(ta)守口(kou)如瓶，寧死不屈。劉(liu)(liu)平(ping)(ping)楷(kai)(kai)被捕(bu)(bu)后，中(zhong)共(gong)黨(dang)(dang)組(zu)(zu)織(zhi)(zhi)及劉(liu)(liu)平(ping)(ping)楷(kai)(kai)親屬曾積極組(zu)(zu)織(zhi)(zhi)營救(jiu)，均未奏效。
7月，正(zheng)值中共(gong)云南地(di)方組(zu)織發(fa)動(dong)陸良(liang)暴動(dong)，國民黨(dang)頑(wan)固派(pai)驚(jing)恐(kong)萬狀，急速密令(ling)槍殺(sha)劉平楷。7月26日午后(hou)2時30分，以”赤化代表”、“勾(gou)結迤(yi)南匪黨(dang)圖謀不軌”等罪名(ming)，將劉平偕、張(zhang)舫帶到(dao)獄中一空地(di)秘密殺(sha)害。
年僅28歲的(de)(de)(de)劉(liu)平楷英勇就義(yi)后，在(zai)昆親友劉(liu)百川、張尊五找(zhao)到(dao)鐘祥寓(yu)伙同苦力6人等把他安葬在(zai)昆明北門(men)蓮花池義(yi)冢內，墓(mu)(mu)前豎有石碑，鐘祥寓(yu)在(zai)上面(mian)用毛(mao)筆寫(xie)了(le)“彝良劉(liu)平楷履(lv)端(duan)之墓(mu)(mu)”幾個字(zi)。1931年2月，幾位(wei)彝良旅昆同鄉還曾去奠祭(ji)掃墓(mu)(mu)并合影留念。但后來，時光流(liu)逝，時事變(bian)遷，蓮花池邊(bian)的(de)(de)(de)亂墳早已不(bu)復存在(zai)，烈(lie)士墓(mu)(mu)也被(bei)滄桑(sang)的(de)(de)(de)塵埃(ai)掩沒，不(bu)知蹤(zong)跡。
歲月靜好
