Small ideas in life

Business cards are what we are used to most. More than ten dollars can print 100 cards. After all, business cards are business cards, not paper money. People often put the business cards of door-to-door salesmen aside or even throw them into the trash can. Can the salesman print back-up materials such as calendars, telephone lists, train schedules, or special information of a certain group of people on the back of the business card to increase the preservation value?

At present, I have been making a fuss about mobile phone screens, such as blue screens and color screens. Mirrors are widely used in daily life. But men are not used to carrying mirrors with them every day. Can you combine a mobile phone with a mirror to make a mobile phone that can be used as a mirror?

Outdoor advertising billboards can be seen everywhere in most busy places. In rows of similar billboards, how to strengthen the identifiability and catch everyone's attention? I remember that spring festival couplets should be posted in the countryside. The red paper of Spring Festival couplets is coated with something similar to tin foil in the inner box of cigarettes, which will flash slightly. Can you embed a little tin foil on the outdoor advertising billboard to make the billboard shine a little golden light under the sunlight, so as to attract people's attention?

Newspaper advertisements have been hovering in the print and graphics of newspapers. Can cosmetics and perfume advertisements buy out the distribution rights of a certain newspaper on a certain day and put perfume (like scented stationery) on that day's newspaper? The smell of the newspaper is overflowing, will it cause a small sensation and make the perfume brand a household name?

Besides radio, television, newspapers, magazines and other mass media, can we find another propaganda carrier in another way? We buy vegetables or fruits every day, and vendors will give away disposable plastic bags for free. These plastic bags are translucent and have no printed information. Since supermarket shopping bags can print advertisements, why not print advertisements on these plastic bags? Imagine that in ten days and a half, all disposable plastic bags in the streets and alleys of a certain block are printed with public service advertisements, which read "Announcement of a certain enterprise". What effect will it have?

Although my idea may not be feasible, the purpose is to attract jade. When we innovate together, someone will always come up with good inventions and wonderful ideas to improve our lives.
