1.LED advertising, this concept is very general. Nowadays, most of the luminous signs you can see along the street are built-in LED light sources except those with light cloth. Then there is the LED display. Therefore, there are a wide range of consumer groups, and there must be signboards where business takes place, and LED lights where there are signboards. What the industry does well is to seize a certain brand sector, such as financial system (bank), gas station, automobile sales sector and other consumer brands. Relatively speaking, the consumer groups of LED display screens are relatively single, not to mention those in front of small shops, and the public information sector is the focus, such as square rental spaces, bus advertising spaces, street signs and so on.

2. Server computer hardware, that is, those technical service companies on the market. Demand groups are also very wide, let's say a few high-level high-quality groups, such as foreign-funded companies, government agencies, star-rated hotels, sales companies with sales networks (car 4S shops, supermarkets), banks will not say anything, and the qualification requirements are too high. But the more qualifications you have in this field, 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 earn, 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.

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

4. There are many types of wedding companies, some rely on drinks, dresses, wedding cars and catering, and some rely on planning, tourism, business etiquette and star relations. Of course, if you are strong enough, you can cooperate with dating programs or matchmaking websites and bundle them for sale. To tell the truth, in the years when the marriage collapsed and the post-80s economy was tight, everyone tried to keep a low profile and save money to deal with the marriage problem. Market demand is weakening.

In these four industries, the competitiveness of advertising signs is relatively weak and the market is broad. Of course, in the end, we should choose a sure industry according to our actual background.
