How to create multiple version of single post

I am willing to create 2 pages for selected posts I have written. One in English language and another is in Hindi.

Why not translator ?

Translator translates many words in typical Hindi which makes a topic unclear to understand(even by myself). I want to keep combination of both Hindi & English words.

1. Create another post under same categories with same title but _hi in last of paramlink.
2. Then add one more tag to all your hindi posts, say hindi.
3. Now exclude all the posts of hindi tag from default search or index.
4. Do the same with your English posts.
5. Give an option to opt language on all pages.
6. Filter posts as per selection.
