look at the points!

1.LED advertising, this concept is very general. Nowadays, the luminous signboards you can see along the street are mostly built-in LED light sources, except those with light cloth. Then there is the LED display. Therefore, the consumer groups are relatively wide, and signboards are needed where businesses occur, and there are LED lights where signboards are located. What is done well in the industry is to seize a certain brand section, such as financial system (bank), gas station, automobile sales section, and other consumer brands. Relatively speaking, the consumer groups of LED display screens are relatively simple, not to mention those at the door of small shops, and the public information section is the focus, such as square rental space, bus advertising space, road signs and so on.

2. Server computer hardware, that is, those technology service companies on the market. Demand groups are also very wide, let's say a few high-level high-quality groups, foreign-funded companies, government agencies, star-rated hotels, sales companies with sales networks (car 4S shops, supermarkets), banks do not say, the qualification requirements are too high. But the more qualifications you have in this business, the better. You also need a communication platform (optical fiber) as the backing. If you simply buy and sell equipment, there is no money to make, and the market transparency is too high. You mainly sell services, such as buying an IBM server or Cisco routing. You need engineers with relevant qualifications.

3. I don't know what a freight forwarder is. I hope that it means debt and credit. Need to have a huge capital chain.

4. There are many types of wedding companies, which are developed by drinks, dresses, wedding cars and catering, and by planning, tourism, business etiquette and star relations. Of course, if you are strong enough, you can cooperate with dating programs or matchmaking websites and sell them in bundles. To tell you the truth, in the years when marriage collapsed and the post-81s economy was tight, everyone tried to keep a low profile and save money to deal with the marriage problem. The market demand is weakening.

in these four industries, there is relatively little competition and a wide market for advertising signs. Of course, in the end, you should choose a sure industry according to your actual background.
