My wife holds an American green card. My wife is older than me 14 years old. Will she be refused a visa because of her immigration tendency and fake marriage?

Yes, your question is just like what you said! It is very easy and logical for visa officers to think of the same problem!

In any country in the world, people have basically the same idea about the age of marriage! China is like this, and the United States is exactly the same! What's more, you are from China, and your marriage must first conform to the local conditions and customs of China!

Therefore, in this case, it may be very obvious that you refuse to sign. If you say that your marriage is real, your feelings are real, and it's not about immigration, you need more powerful information than other cases of marriage reunion. First of all, your reason can be trusted by the normal people around you. Only when what you say is reasonable can you convince the visa officer! Good luck!
