On March 25, 2026, Song Baek-kyung took to Instagram with a post that tossed a long-standing question to fans — and urged everyone to crack it together.
The image featured an eye-catching graphic breaking down various Hanja (Chinese characters) and their meanings. Zeroing in on the character "益," Song asked followers versed in Hanja to weigh in. He openly shared his curiosity about Japanese and Hanja, actively inviting people to join the conversation.
Fans responded in droves. A deep-dive discussion sparked over the differences between handwritten forms and computer fonts. One Korean fan even noted that complex characters like this can be challenging for native Japanese speakers, echoing the sentiment across the comments.
