What was the name of second-hand housing transaction in ancient times?

Second-hand housing transactions were called "Yaozhang" in ancient times (called "Yaotie" in Yuan Dynasty).

In the series "Wild Guest", Dong Fangshuo wrote a sentence: "Between the rich pickaxes, the number is earth paste, and its price is one mu of gold." This is the most familiar land near Chang 'an in Han Dynasty. The so-called one gold in the Han dynasty refers to a catty of gold, which is converted into almost 10 thousand copper coins, and now it is converted into four or five thousand. An acre of land is more than 660 square meters, with 70 to 80 yuan per square meter. There are many records that can prove this price, such as "the paste of Jue Tu, the price per mu is one gold" and "the ancestral land is fertile and the price per mu is one gold". This is probably the price of the Han Dynasty.

In the Song Dynasty, real estate transactions became active. You can not only buy it with money, but also exchange things. "Talk about Tiewei Mountain" said that calligrapher Mi Fei wanted to buy a big house in Danyang, south of the Yangtze River, and asked people everywhere. One of his buddies is thinking about a treasure in Mifei's hand. What is this? An inkstone. This inkstone is called the inkstone mountain, which originally belonged to Li Houzhu. It is more than a foot long. There are 36 finger-thick "peaks" in front, slopes on both sides and a research pool in the middle. It's a good baby anyway. So, this one helped Mifei to explore that place, and finally found an ancient tomb under the river in Kanluoji, which is said to be the residence of people in the Jin and Tang Dynasties. It has beautiful scenery, mountains and rivers behind it, and many towering ancient trees. After that, I called a dinner party, and everyone ate and drank happily together. Mi Fei changed the land from inkstone. Later, he built a big house here and named it "Haiyue Temple".
