Tang Jian can be described as a young man.

His father Tang Jian was friendly with Tang Gaozu Li Yuan, and when Li Yuan raised troops in Taiyuan, Tang Jian participated in the planning. In the second year of Wude, Tang Jian and Li Xiaoji, the king of Yong'an, were captured by Liu Wuzhou, and learned from Yuan Junshi in prison that Dugu Huaien was going to rebel. Dugu Huaien was stationed in Puzhou at the time, and Tang Jian sent people to expose Dugu Huai'en for rebellion. After Li Shimin defeated Liu Wuzhou, Tang Jian worshiped as the secretary of the Ministry of Rites, awarded the history of the governor of the Tiance General's Mansion, and was awarded the title of Duke of Juguo, and was specially exempted from the death penalty once.

From the above resume, it can be known that Tang Jian is not only a hero from the dragon, but also quite discerning when choosing a side and standing in line, and tied himself to Li Shimin's chariot early. At the beginning of the Tang Dynasty, he was a good general and a virtuous minister, and the Li father and son never rewarded the ministers of the court, but the honor of "special exemption from capital crime once" was only obtained by Tang Jian, which shows that his honor is very great.

Tang Jian is low-key, not inconspicuous, when it comes to the famous ministers of the early Tang Dynasty, many people will think of 'Fang Mou Du Dudu', think of the eldest grandson Wuji, think of Chu Suiliang and others, few people will think of what Tang Jian has done, but his status does not have to be low by anyone, he has never participated in the factional struggle between the DPRK and China, and he is considered a neutral faction, but whether it is a new nobleman, or five sects and seven surnames, no one dares to look down on him, because he is a bargaining chip outside the two ends of the balance that has been balanced, no one wants to offend him, and let him join the other faction. Tang Jian also understands in his heart, so he often pretends to be confused, if he can, he doesn't express his position, and he doesn't pay much attention to the things he does, drinking and writing poems all day long, unless it is a task personally assigned by Li Shimin, he leaves the rest of the things to his deputy to do. Therefore, there are often officials who participate in his negligence in political affairs, and he doesn't care, he still goes his own way.

This time he was an envoy to the Turks, and for the rest of his life, Li Shimin renamed him the secretary of the Ministry of Civil Affairs. From the Ministry of Rites to the Ministry of Civil Affairs, although the official rank is the same, one is an ornament, and the other is real power. But Tang Jian was not happy, because after he became the secretary of the Ministry of Civil Affairs, he needed to do more. And the people's livelihood situation in the early Tang Dynasty was not optimistic, either there was a disaster here, or there was a flood, and every day there were places to ask for disaster relief posts to be handed over. And these things need to be seen and checked by him personally. Tang Jian, who had always been lazy, suddenly became busy, very uncomfortable, and he was over fifty years old, and his physical strength was not in a hurry, so he was a little overwhelmed. I didn't bother to watch the singing and dancing, I just feasted and drank, and I basically rested when I got home from the official office every day, and I didn't even pass on a concubine.

Life changes before the end of October.

On that day, he was in charge of the government, and suddenly his family came to report, saying that an old friend came to the door, and after careful questioning, he learned that Li Mu sent his mother over. Tang Jian hurried home and saw Wang Hu who was escorting, and after learning the antecedents, Tang Jian didn't say a word, cleaned up a courtyard in the Guogong Mansion, and settled the Sun family.

A few days later, Tang Jian returned home from the official office, and his family told him that Sun took advantage of the inattention of the maid who was waiting, and begged for death, but fortunately, the maid came back in time and was rescued. Tang Jian was shocked, although he was lazy in political affairs, he attached great importance to personal faith. On that day in the Turkic camp, although it was an urgent word, since he promised Li Mu 'your mother, I will raise her', he will do his best to do it. Li Mu returned to defend the city, it is also a move of faith, life and death are uncertain at this time, if he comes to find his mother in the future, do you want to tell him that your mother I didn't take care of it, hanged himself?

Tang Jian hurriedly came to the backyard where the Sun family lived temporarily, and comforted him for a while. Sun said that his son had not been heard from for so long, and most of them were dead. She is alone in this world, what is the meaning of living, it is better to die. In order to persuade Sun, Tang Jian took himself as an example. It turned out that Tang Jian's wife passed away more than ten years ago, and the two had a very strong relationship, and the death of his wife hit Tang Jian very hard. Over the years, I have been neglecting political affairs, also because I have no mind, singing, dancing and drinking, just to divert my attention and not miss it.

When Sun saw Tang Jian talking about emotion, her eyes were full of tears, moved by his deep affection, and she also told about the past between her and Li Mu's father, Li Kang. The two of them just said a paragraph by themselves, and before they knew it, they talked about it until dawn.

After this night of conversation, Sun's voice and appearance were engraved in Tang Jian's mind. I dreamed of him in my dream, woke up and thought of her, and I couldn't concentrate on handling government affairs, and I looked forward to coming back from the government office as soon as possible every day, so that I could find an excuse to chat with Sun. After a long time, the subordinates in Tang Jian's mansion have seen the clues, and Grandpa Guo is afraid that he is interested in this original lady of the Sun family, and when he treats the Sun family, his attitude is more respectful. And Tang Jian and Sun, who were in it, were unaware of this. The window paper has not been pierced, and the relationship between the two has stopped at chatting every day and comforting each other.

Until yesterday, a letter was sent from the Cao Guogong Mansion that Li Mu had come to Chang'an, and he was going to pick up his mother for a reunion tomorrow. Hearing this letter and thinking of the imminent separation, Tang Jian recognized his feelings, and suddenly, the feelings in his heart became complicated.

He was already fifty-one years old, and Sun, he had already asked, was only thirty-six after the New Year. Although with his status, marrying a young concubine is not a problem at all. But in the face of the Sun family, he didn't dare to say the word 'concubine', because in his opinion, it was a kind of blasphemy against the Sun family.

But if you want the media to get married, it is also difficult to do. In the Tang Dynasty, marriage was relatively free, not to mention that the husband died and married again, or remarried after the divorce, no one would say anything. But after all, Tang Jian is the respect of the country, and he is a powerful man for several generations, marrying a folk woman, or a second marriage, is somewhat unreasonable. Tang Jian was worried in his heart, but he still told the Sun family the news of Li Mu's arrival in Chang'an.

The Sun family, on his side, also realized his feelings for Tang Jian. Thinking of the separation, the sorrow in my heart was like when I heard the news of Li Mu's father Li Dang's death more than ten years ago, but in the face of the choice, the Sun family still resolutely chose his son, so when Li Mu came to the door, the Sun family had already packed up the baggage, and she was already planning to give up this feeling, go with her son, and leave the Juguo Mansion.

For Li Mu, he couldn't imagine that the old lady would have feelings for Tang Jian by borrowing a few of his brains, he is not the kind of person who eats the old and has a hostile attitude towards his mother's marriage, but in his thoughts, the age difference between these two people is too much. In the words of later generations, Tang Jian can be Sun's father no matter how old he is, and the age difference of his teens, he will not think about it.

Therefore, he thanked him, gave gifts, and then politely refused Tang Jian's banquet, and then left with Sun's farewell.

Before leaving, Tang Jian was sent to the door, Sun Shi boarded the carriage, listened to Li Mu and Tang Jian's goodbye, and couldn't help but open the curtain and look out.

Just as Tang Jian also looked over, the two looked at each other, and their hearts jumped. Sun hurriedly lowered the curtain, Tang Jian reluctantly withdrew his gaze, and said to Li Mu: "Take good care of your mother." ”

After Li Muying got down, he added in his heart: I don't know if there is a chance to meet again.
