Have the advantages of your product, brand, design, price and function, plus your contact information and address, etc.
If you make a "green design", you can print something useful or interesting on the back, so that others will not throw it away when they are not interested.
I have seen a leaflet of a tea bar in our school with a detailed schedule of the Beijing Olympic Games printed on the back. I've watched it for a long time.
You can also print the calendar of 2008 or an interesting story.
See if you want to invest more in color printing with better paper or save black and white printing on ordinary paper.
Post advertisements on the bulletin board of each student apartment building.
There are other places to post.
Dog skin plaster is also acceptable. It's uncivilized, but it's repeatedly banned. It's up to you.
There is also a DM leaflet, which is sent to every dormitory (stuffed through the gap at the bottom of the door)
Of course, someone can also sell it directly to him.
It's a bit difficult to publicize slogans. It depends on what kind of slogan you take.
Some are sensational, some are simple, some are arrogant, some are funny, and some ridicule competitors. For example, I am still wonderful without heaven! I imagined it myself, or it was sensational. For example, although it is not as beautiful as heaven, I still have the confidence to protect you. Imitate anyone who is not like you. For example, you only buy suitable umbrellas, not expensive ones. Your best escort, hahaha, is all my imagination. It's up to you. )
