時光荏苒,一(yi)日,殷溫(wen)嬌小姐(jie)在(zai)府衙正(zheng)思念丈夫及家人,忽(hu)感腹(fu)內疼(teng)痛,暈倒在(zai)地(di),不(bu)覺(jue)生下(xia)一(yi)男嬰。劉洪回府見此(ci)(ci)惱(nao)羞成(cheng)怒,欲掩殺嬰兒,殷溫(wen)嬌小姐(jie)道:“今日天色(se)已晚,容明日拋去江(jiang)中。”恰巧(qiao)次(ci)日早晨,劉洪府衙內有緊急公務外(wai)出,那殷溫(wen)嬌小姐(jie)便(bian)寫了血書(shu),并(bing)將男嬰一(yi)腳趾咬下(xia),以此(ci)(ci)作為日后(hou)驗記,然后(hou)放在(zai)一(yi)木板上從江(jiang)中漂流(liu)而(er)去,此(ci)(ci)子一(yi)直(zhi)漂至金山(shan)寺邊(bian),被眾僧打撈搭救。
日月(yue)如(ru)梭(suo),不(bu)覺此(ci)子在(zai)寺內度過(guo)十八(ba)(ba)載,長老叫他削(xue)發修(xiu)行,取名玄(xuan)奘(zhuang)(zhuang),他就(jiu)是(shi)后來(lai)歷經(jing)(jing)九(jiu)九(jiu)八(ba)(ba)十一(yi)難到(dao)(dao)天竺國取經(jing)(jing)成佛的唐三藏(zang)。玄(xuan)奘(zhuang)(zhuang)長大后,經(jing)(jing)常與眾僧談(tan)經(jing)(jing)論佛,有一(yi)酒(jiu)肉和尚(shang)因(yin)講經(jing)(jing)參禪被(bei)玄(xuan)奘(zhuang)(zhuang)難倒,便罵玄(xuan)奘(zhuang)(zhuang)無父無母(mu),玄(xuan)奘(zhuang)(zhuang)哭(ku)訴長老,長老將真情告(gao)知(zhi)玄(xuan)奘(zhuang)(zhuang),玄(xuan)奘(zhuang)(zhuang)在(zai)長老的幫(bang)助(zhu)下,借口(kou)化緣僧鞋,到(dao)(dao)江州府(fu)與母(mu)親(qin)殷溫嬌相見(jian),母(mu)子抱頭痛哭(ku),當(dang)即殷溫嬌修(xiu)書一(yi)封,告(gao)知(zhi)玄(xuan)奘(zhuang)(zhuang):“你(ni)奶(nai)奶(nai)可能仍在(zai)洪(hong)州城萬花店,當(dang)今丞(cheng)相殷開山是(shi)你(ni)外公(gong),到(dao)(dao)長安(an)時,你(ni)可將信(xin)交于(yu)你(ni)外公(gong),替你(ni)父親(qin)報仇。”
玄(xuan)奘一路乘船來到洪(hong)州(zhou)(zhou),找(zhao)到萬花店主劉(liu)小二,聞其奶奶因無盤(pan)纏早已(yi)上街乞(qi)討(tao)度日(ri),住(zhu)在城(cheng)南一個破(po)瓦窯里。玄(xuan)奘找(zhao)到奶奶,交了一些銀兩,仍(reng)安置到劉(liu)小二店內(nei)棲身,即刻(ke)趕赴長(chang)安。殷丞相知道真相后(hou),稟唐太宗(zong)李世(shi)民欽點御(yu)林軍(jun)即日(ri)趕赴江州(zhou)(zhou),捉拿水(shui)賊劉(liu)洪(hong)并(bing)將其押(ya)回原籍洪(hong)州(zhou)(zhou)城(cheng)(今山東(dong)省(sheng)德州(zhou)(zhou)市齊河縣劉(liu)橋鄉流洪(hong)村),在洪(hong)江渡(du)口(kou)剜(wan)取心肝,祭了陳光蕊,百姓無不拍手(shou)稱快。
傳說劉洪殺死(si)陳(chen)光蕊(rui)后(hou),尸(shi)首(shou)沉在水底不(bu)動(dong)。此事驚(jing)動(dong)東海(hai)(hai)龍王(wang),原來陳(chen)光蕊(rui)放(fang)生的(de)那(nei)尾金(jin)色鯉魚,正是(shi)東海(hai)(hai)龍王(wang)。龍王(wang)感其(qi)救(jiu)命之恩,急命手下(xia)到洪州城隍廟取了陳(chen)光蕊(rui)魂魄,將尸(shi)體運至(zhi)東海(hai)(hai),并在其(qi)口內放(fang)入一顆(ke)“定顏珠(zhu)”,日(ri)后(hou)好(hao)讓(rang)其(qi)還(huan)魂蘇(su)醒,一報前仇。
劉洪在(zai)洪江(jiang)渡(du)口伏法,玄奘與其母親(qin)在(zai)江(jiang)邊哭祭陳(chen)光蕊,忽(hu)見(jian)水面上一(yi)(yi)個死尸(shi)浮來(lai),殷溫(wen)嬌靠近(jin)一(yi)(yi)看,認出正是(shi)丈夫的尸(shi)首,嚎啕大哭。哪知尸(shi)體竟(jing)(jing)然逐漸舒展開來(lai),最后竟(jing)(jing)爬了起來(lai),原(yuan)來(lai)龍(long)王(wang)(wang)將(jiang)陳(chen)光蕊魂魄收取后一(yi)(yi)直等待(dai)這一(yi)(yi)天,于是(shi)龍(long)王(wang)(wang)急派手下將(jiang)陳(chen)光蕊口內塞入一(yi)(yi)顆還魂丹,送回洪江(jiang)與家人團聚。
玄(xuan)奘與(yu)其父母(mu)、外公一(yi)起高高興興趕到洪州城(cheng)萬(wan)花店與(yu)奶奶團(tuan)聚,住了一(yi)宿,第二天一(yi)早準備啟程赴長安時,忽然不見了殷溫(wen)嬌,城(cheng)里人說殷夫人因(yin)遭受屈(qu)辱已投江自盡。
后(hou)人有感于殷溫嬌的貞烈(lie),遂將洪江改為溫聰(cong)河。
唐玄奘(zhuang)西天取經(jing)成功后,帶(dai)領(ling)徒弟(di)孫悟空(kong)曾(ceng)到洪州城修建了一座金福(fu)寺(si),一來是傳播印度大乘(cheng)佛(fo)教,二(er)來超度母(mu)親(qin)的(de)靈(ling)魂。取經(jing)前傳播的(de)是小乘(cheng)佛(fo)教,小乘(cheng)佛(fo)教是教化人們相信因果(guo)關(guan)系,而大乘(cheng)佛(fo)教則是可超度終生,據說唐玄奘(zhuang)將母(mu)親(qin)超度成了一只(zhi)美(mei)麗的(de)鳳(feng)凰,每到金福(fu)寺(si)有重大佛(fo)事(shi)時,這只(zhi)鳳(feng)凰都飛到金福(fu)寺(si)上(shang)空(kong)鳴叫盤(pan)旋,前來助興(xing)。
劉(liu)洪(hong)伏法后(hou),人(ren)(ren)們極其(qi)痛恨劉(liu)洪(hong),就(jiu)把這個可惡(e)的(de)水(shui)賊埋葬在流(liu)洪(hong)中心街的(de)十字(zi)路口,并在那里(li)設立集市,讓千夫所(suo)指的(de)劉(liu)洪(hong)承受萬人(ren)(ren)踐踏,永(yong)世不(bu)(bu)得翻(fan)身(shen)。舊時流(liu)洪(hong)的(de)集市非常熱(re)鬧,每逢趕集之時人(ren)(ren)來人(ren)(ren)往、車水(shui)馬龍、川流(liu)不(bu)(bu)息,是方圓幾十里(li)之內的(de)最(zui)為繁(fan)榮(rong)的(de)市鎮。如今流(liu)洪(hong)集已易址(zhi)異(yi)地。后(hou)來百姓因(yin)惡(e)于劉(liu)洪(hong)其(qi)名,將洪(hong)州城(cheng)改為流(liu)洪(hong)。
