At this time, there were shipyards in Datang, mainly focusing on the generation of Huainan road and Jiangnan Road.


    Perhaps it is because they face the sea that people who see coastal areas are more sensitive to the use of waterways.


    But inland, the water system is developed, but it has become a decoration.


    The land of Guanzhong has been said to surround Chang''an with eight rivers since ancient times.


    "The eight rivers flow in different directions, which are opposite to each other.". Sima Xiangru''s famous Ci Fu Shanglin Fu has a few sentences that show the beauty of Shanglin garden in the Han Dynasty, and it is a detailed description of the eight rivers around Chang''an.


    Among the eight rivers, the Weihe River flows into the Yellow River, while all the other seven rivers flow into the Weihe River. Even if you can''t walk a big ship, with today''s Datang ships, ships below 100 materials can easily get through.


    But officials in Chang''an just regard these waters as irrigation water sources and completely ignore the shipping capacity.


    Recalling the bustling streets of Chang''an and the dense traffic of ox carts and camels, Tang Hao finally realized at this moment that he could take the waterway to alleviate this situation!


    Popularize waterways, so that the people in the north and South waters of the Tang Dynasty can exchange grain and oil and enhance contacts.


    Let the inland and coastal areas exchange what they need, the precious plateau herbs are introduced into the coastal hinterland, and the strange fish, shellfish and seafood are introduced into the inland areas. Isn''t it the best of both worlds?


    At that time, if you simply build several docks and warehouses, you can enjoy the continuous dividends brought by water transportation. Why didn''t you think of it earlier?


    This is a windfall!


    Tang Hao slapped him on the knee and blurted out.


    "Yes! If you are used to riding horses, your mind is solidified, and you can''t turn around all the time."


    The sudden move startled Li Zhi, who was immersed in imagination.


    When he hurriedly moved away from his position, he looked over in fear.


    "Why are you so excited?"


    "Fixed thinking? What is this?"


    As soon as he grabbed Li Zhi''s arm, Tang Hao grinned and said.


    "Do you want to see the blue mirror like sea? Do you want to see the snow-white bear? Do you want to see the giant whale?"


    The mere description aroused the child''s curiosity.


    His eyes lit up a curious light, and Li Zhi nodded heavily.


    "Think!"


    Hold Li Zhi down and sit in the carriage again. Tang Hao sets a goal for Li Zhi.


    "OK! When you go back to Chang''an, you will mention it to your sister. You must convince her!"


    "Then I will ask your majesty to take you with me."


    Princess Changle has lived in the palace for a long time and rarely walks around. She has formed a quiet character over the years.


    Although he is now his wife, he must obey his words.


    However, Tang Hao still hoped that Princess Changle would follow her on this trip, not in the tone of her own command.


    ……


    Bumpy all the way, dragging a single shirt that can twist out of the water, I finally approached Chang''an, which has been away for many days.


    Looking at the ancient city wall full of historical vicissitudes, Tang Hao was quite kind.


    It was still a bustling stone road into the city. The fat body in the cage became the focus of attention. Many Chang''an people looked at it and pointed together.


    Chumo and Su Qingjie, former comrades in arms in the barracks, had already met at the gate of the city.


    Pick up the carriage, exchange greetings, talk about the worries of the court, the situation of the Marquis house, and the progress of recruits'' training.


    Amid the laughter, the Marquis house was near.


    Chumo jumps out of the carriage, takes over the prisoner and looks at Dali temple, waiting for the interrogation.


    Su Qingjie succeeded Wu Tong''s coachman and took the initiative to send Li Zhi back to his house.


    When they left, they didn''t forget to make fun of each other.


    "Hurry back to the house. Don''t let the two beautiful women wait!"


    Ha ha, in the laughter, it happened that two beauties came out of the house to meet them. When they heard their teasing, Yuyu''s face was flushed.


    Arm over the two wives, through the mansion, straight back to the north house.


    After a long hesitation, Princess Changle finally asked.


    "Is everything going well in Qingzhou?"


    Seeing the worry in Princess Changle''s eyes, Tang Hao slowly put away his smile.


    Princess Changle must have heard some rumors about the relationship between King Li Tai of Wei and Qi Feng.


    Qi Feng was arrested, and Li Tai, king of Wei, was naturally involved.


    But king Wei is the eldest brother of Princess Changle and protects Princess Changle everywhere.


    Once upon a time, Li Chengqian, the eldest brother of Princess Changle, was demoted to Qianzhou because of a mistake made by the court. So far, there has been no news.


    Princess Changle was only worried that Li Tai would follow in the footsteps of Li Chengqian.


    Big hands stroked Qingsi. Tang Hao stared at the complicated figure in front of him and said softly.


    "The guard of Qingzhou has been secretly executed by me. As for Qi Feng, it is a secret letter to your majesty. Only me and the king of Jin know the royal highness of Wei behind him."


    "Don''t worry, this matter will only be handled secretly by your majesty and will not be published in the court."


    Princess Changle raised her face fiercely, bumped her head into her solid chest and said softly.


    "Thank you, husband."


    "You know... I have only such a brother in the imperial city."
