Hello @hoaithu, sorry for the inconvenience but I have been following your work and wanted to congratulate you. I have decided to do a concert with my band highlighting the ability of music to unite a whole world. Regardless of the language or country. And I wanted to see if you wanted to collaborate, just by sending a small video inviting people to attend, we would give your name and invite our followers to see your work ... I hope you are interested, and respond to this message ...
