I have not paid the annual fee for my patent for 2 years. Is it possible to reapply?

Cannot.

If you have not paid the annual fee for two years, the patent rights have long been abandoned. However, the patented technology has constituted existing technology. Submitting a patent application again for the same technology does not comply with the provisions of repeated authorization in Article 9 of the Patent Law. As well as the provisions on novelty and inventive step in Article 22, Paragraphs 2 and 3 of the Patent Law, re-application cannot be made.
