Band group CNBLUE's member Jung Yong Hwa revealed a picture of themselves that came out in a music textbook in Thailand.

On May 28, Jung Yonghwa posted on his Twitter, "Everyone! It's been a while. Thank you once again for Blue Moon Seoul."

About the picture, Jung Yonghwa said, "I heard we came out in Thai textbook but it feels different to be seeing it ourselves! Thank you to Thai fans! We will try to go visit you soon again! Thank you for the great love and support all the time!"

The textbook is a basic music book for 12th graders in Thailand and it introduced CNBLUE as a "trendy and sentimental music band."
