"Xiao Han, I won't say much else to your grandfather. Being too smart isn't necessarily a good thing. Remember to hide your shortcomings, okay?"
"I will keep in mind what my grandparents said."
"Everyone, go and rest. We have to get up early tomorrow to travel. We will meet again next time. There is no need to be sad."
"Good Grandmother"

After breakfast, Liu Yuhan, Huo Dong and others carried the gifts sent by the Liu family and the dried prey furs back home.
This time they took Huo Dong's private wooden boat to the Haiyu Port. The wooden boat was small but quite fast.
The most primitive ancient large ships mainly relied on three sources of power for propulsion: wind power, human power, and water power.
By this dynasty, the stern rudder had developed and become increasingly perfect and mature.
Based on the vertical rudder, the hole rudder and the balanced rudder were developed. The hole rudder has diamond-shaped holes on the rudder blade to allow water on both sides of the rudder blade to flow, thus reducing the resistance when operating the rudder.
A balanced rudder is one that expands the area of the rudder blades so that they extend in front of the rudder stock, and the rudder blades before and after the rudder stock are nearly consistent, thereby making the water pressure more balanced, which can also reduce the resistance when operating the rudder.
During this dynasty, ships had already developed elevators that could be raised and lowered according to the depth of the water. When the water was deep, the rudder could be lowered to improve its efficiency; when the water was shallow, it could be raised to protect the rudder.
There were many types of ship rudders during this period, and the ancients could choose different rudders according to the needs of navigation.
Liu Yuhan once again marveled at the wisdom of the ancients.
After getting off the boat, Huo Yi pulled their previous carriage out of the inn.
By noon, they had returned to Changping County. After having a quick bite to eat at a restaurant, Huo Dong, Liu Yuhan, and the others parted ways.
The master returned to Fulai Village with Liu Yuhan. Grandma Qin, who wanted to stay on the island to look after Madam Liu and the others, was asked to return with Liu Yuhan and the others. Grandma told her to teach Liu Yuhan and the sisters about manners and behavior, based on their status.
Liu Yuhan was not opposed to this. Since she was already in this dynasty, she might as well follow the local customs. It would always be good for her and her sisters to understand more rules.
The sun sets in the Liu family courtyard.
The return of Liu Yuhan and the others surprised the family! Mrs. Li hurriedly cooked a few more dishes with the two little girls.
Xiao Si and Xiao Wu happily circled around their parents and sister, chattering about what had happened in the past few days.
They are actually still six-year-old children, and their emotions are only shown on their faces. They really miss their parents and sister so much!
Liu Yuhan listened to them quietly, answered their questions patiently, and agreed with them from time to time.
She was very relaxed and felt very comfortable in this family atmosphere.
