Recently, AB6IX fans were touched as member Donghyun taught his fans how to say "Thank you" in sign language and revealed the reason he learned it.

On January 20th, Donghyun logged onto Vlive and took the time to communicate with his fans. On this day he explained that he had learned sign language and learned how to say "thank you."

He told his fans he wanted to tell them how to say thank you and began sharing the story behind why he learned sign language. He explained that he had to take a taxi recently and when he got on the taxi, he confirmed it was the correct taxi by asking the driver to confirm. However, the taxi driver didn't reply nor did he look at him. Donghyun thought that the taxi driver was angry and wondered if he had done something wrong.

That's when he saw a note on the back of the seat that said, "This is a taxi is driven by a hearing-impaired person. Please tap the driver on the shoulder if you would like to say something." Donghyun then explained, "After seeing that note, I felt bad for thinking that the driver was mad or something. So I decided to learn how to say 'thank you' in sign language."

Donghyun explained that he wanted to say thank you properly to the taxi driver so he searched on YouTube a tutorial on how to say 'Thank you' in sign language and learned it on his way. Then when he was getting off of the car, he tapped the taxi driver on the shoulder to thank him.

Donghyun concluded by telling his fans to learn sign language because they might get in a taxi driven by a hearing-impaired driver as well. He said "I'm not telling you guys to get compliments, I just think it would be nice for our fans to do this for the drivers. That's why I'm telling you guys this."

After seeing Donghyun's video, netizens commented, "Donghyun's so nice," "He's good looking and he has a kind heart," "He has such a deep heart," "I never knew there were hearing-impaired taxi drivers," "I can't believe he searched on YouTube in that short time and practiced it. This is how nice he is," "I'm going to memorize how to say 'thank you' too," "This was so nice to hear," and "My heart became so warm from hearing his story."
