悲喜不一 Grief and Joy in One Heart
太宗聞言,心中悲喜不一。喜者,誇獎魏徵好臣,朝中有此豪傑,愁甚江山不穩?悲者,謂夢中曾許救龍,不期竟致遭誅。只得強打精神,傳旨著叔寶將龍頭懸掛市曹,曉諭長安黎庶。一壁廂賞了魏徵,眾官散訖。太宗闻言,心中悲喜不一。喜者,夸奖魏征好臣,朝中有此豪杰,愁甚江山不稳?悲者,谓梦中曾许救龙,不期竟致遭诛。只得强打精神,传旨着叔宝将龙头悬挂市曹,晓谕长安黎庶。一壁厢赏了魏征,众官散讫。

At these words Taizong's heart was torn between grief and joy. For joy, he praised Wei Zheng as a fine minister — with such a hero at court, why fear the realm would ever be insecure? For grief, he reflected that in his dream he had promised to save the dragon, only for it to come, against all expectation, to this execution.
悲喜不一 is grief and joy mingled, not of one kind — and the sentence lays them out as a matched pair, 喜者 against 悲者, for joy this, for grief that. Pride in his minister on one side; on the other, a promise given and not kept. The second feeling is the seed of everything that follows. 甚 in 愁甚, 'why worry,' is the question-word shén, and 朝 in 朝中 is cháo.
He could only force up his spirits and issue a decree ordering Shubao to hang the dragon's head in the marketplace and make it known to the people of Chang'an. Meanwhile he rewarded Wei Zheng, and the assembled officials withdrew.
強打精神 is forcing your spirits up when they will not rise by themselves, with 強 read qiǎng. The emperor is performing, and the performance is public: 市曹 is the open marketplace, where the head goes on display as a wonder. 得 in 只得, 'could only,' is dé; 著 in 傳旨著, 'to order,' is the directing zhuó; 長 in 長安 is cháng.
Taizong's response is a knot of contradiction set out as a neat balanced pair, 喜者…悲者, for joy… for grief. He is proud of 魏徵, whose loyalty and power make the dynasty secure, and at the same time stricken that his own promise, freely given in the dream, has come to nothing and the dragon is dead in spite of an emperor's word. The parallel construction holds the two feelings in exact balance.
He masks the private disquiet with a public act, hanging the dragon's head in the marketplace as a marvel and rewarding his minister. But the phrase 夢中曾許救龍,不期竟致遭誅 — in the dream he had promised to save the dragon, only for it to be executed — names the debt the rest of the chapter will collect. A sovereign's word, even given in sleep, is not lightly broken, and the wronged dragon returns that same night to ask for what he was promised.
