You can hand out leaflets to people passing by, because everyone is a potential consumer. If you want to show someone the house, first identify whether this person has the need to buy a house. For example, from the age level, people who are slightly middle-aged may have greater demand for housing and their economic ability may be relatively stable.
Then there is your language ability. You can't make people think you are a liar. Because the current social mood is too indifferent, people have to establish high psychological protection. You should introduce your house, price or any preferential treatment to those who are interested in buying a house. ..........
I hope it will help you to say so much.
