Hi @danh.khoa. You are really passionate about food. The dishes you present in your blog all look delicious.
It's a pity that your posts don't get enough visibility on Steemit.
Unfortunately, on such a large blogging platform, users are at risk of not getting the desired results.
Why don't you try participating in some contests organised in the various communities?
This is a great way to gain more visibility and make yourself known on the platform.
Maybe you can find something that suits you in Contest Alerts: Active Contest List where many different competitions organised on Steemit are listed.
Good luck with your blog and do not hesitate to contact me for any information.
