Ooh a double non-answer post. You must really be tilted.
Perhaps you can say why you thought it was important that someone else know how many carriers China has. Adults know how to make statements and not ask childish leading questions.
Here, let me help you, 3rd grader, formulate your answer. Answer these questions to help you understand you own question.
1. How many carriers does the United States Navy have?
2. How many carriers does China have?
3. Why are carriers important, if they are important?
4. How are carriers not important?
5. Does a navy need a carrier?
6. What purpose do carriers serve?
7. What if that purpose cannot be served, are carriers still important?
8. What other Navy ships can serve the purposes of the carrier?
9. What if the carrier is sunk, can other ships continue the purpose of the carrier?
10. Does the number of carrier matter?
