Hello @thienphong and welcome to Hive as I see you're quite new on our platform, so let me drop you a few suggestions to help you navigate better on our platform.

We have different communities on Hive and we're encouraging users to post in the right community based on the topic of the post. This post for example would fit better in Pinmapple community, which is a travel community. OCD community is for topics that don't fit in any other community and should be used when you don't find a niche community for your post.

Here's a guide I put together to help you learn about how communities work and why you should use them -> Communities Explained - Newbie Guide. I also put together a list of communities, which is not complete, there are much more communities on Hive, but it will help you get started.

Once you posted your post in the right community, you can then cross post it to OCD community. Here's a guide about cross posting.

Please don't delete any post with the purpose of reposting it in another community as that can be considered abuse. Leave this post here, you'll get it right next time.
