Hi @kyawzaywin! Look friend this is not the right way of asking for upvotes! The author may take it in a wrong way and some can even flag you if you continued so.

Some of the simple steps that might be helpful for increasing your upvotes can be first of all increase your quality of article, appropriately quote the references you used in writing the respective article. Put the free images related to your article from Wikipedia or pixabay and carry on writing the original content with deep research work.

Moreover, you might engage with other experienced authors, read their articles and raise any queries if you don't know about something in the article. In that way develop a bonding with other which might help you with pretty much improvements!! :)
