google visible meta description with 3 words!!!

Hi guys I have a problem with Google. I created a Landing Page. Its content and graphic are perfect and its meta title and meta description are relevence. I recently discover a problem in Google. The page in SERP has just 3 words in description part!!! I checked all of thing like Schemas and then registered a request for reindexin search console. But there is the problem every times. What do you guess about the problem? What is the solution?
