Public image

The group has been dubbed several nicknames, one of which was "countryside-dols" (countryside idols). The Korean media often uses this nickname due to the fact that all of the members of B1A4 are from the countryside: Jin-young is from Chungju, North Chungcheong Province; CNU from Cheongju, North Chungcheong Province; Sandeul from Busan; Baro from Gwangju, South Jeolla Province; and Gongchan from Suncheon, South Jeolla Province. They were also referred to as "blood-dols" (blood idols) in reference to the origins of their name, as well as "paper-dols" (paper idols) because of the paper classification A4. In an effort to distinguish themselves, B1A4 had also promoted a nickname "saessakdol" (새싹돌, "sprout-dol") and created a so-called "saessakchum" (새싹춤, "sprout dance"), which was showcased in various shows including Quiz to Change the World.


Throughout B1A4's career, B1A4 participated in many goodwill campaigns and donations.

On May 31, 2012, a B1A4 fan posted a post titled 'B1A4 Proves Their Love For Fans' which shared a story of how the B1A4 members visited her home and helped take care of her ill mother. The members took part in this act during theirs days of promoting "Beautiful Target." While B1A4 were over at the fan's home, the members prepared a meal for the family and even volunteered to clean up after the meal and wash the dished. The members then spent quality time with the family taking photos and other activities.

On August 31, 2012 B1A4, donated 140 kg Nanum Store rice garlands to Seoul SOS Youth Camp located in Yang-Cheon. The rice garlands were donated by fans to support Sandeul's musical "The Brothers Were Brave" and "B1A4's Hello Baby." B1A4 decided to donate the garlands to Seoul SOS Youth Camp which was used to feed 1,300 poorly-fed children on a meal. This act of charity brought gratitude to B1A4 and their fans by the head of the youth camp.

On September 1, 2012, B1A4 held a mini concert at the Wonju Market to help raise awareness for traditional markets. This event was created as a celebrity marketing to help traditional markets stay strong in the wave of chain and supermarkets and local convenience stores.

As B1A4 hosted their first solo concert, BABA B1A4, fans from all over the world sent gifts and donations to B1A4, measuring up to approximately 2 tons of rice, 2,356 coal briquettes, 300 eggs, 300 kg of pet food, and 10 mango trees. The group then decided to donate all that were given to them. The 2 tons of rice were donated to a charity of B1A4's choice. The 2356 coal briquettes were donated to provide energy during the winter for those facing energy poverty. The 300 eggs were donated to the Food Bank and the 300 kg of pet food were donated to an animal rescue center. Lastly, the mango trees were donated to Tonj in Southern Sudan through World Vision to help relieve child famine and desertion of the area.

On July 19, 2013, as B1A4 prepared for their second solo concert, AMAZING STORE, B1A4 asked fans for school supplies rather than flower wreaths. As B1A4 is working with CJ’s charity foundation “Donor’s Camp” to support the education of children who are in need, B1A4 asked fans to donate school supplies to help students who are growing up in difficult situations that may hinder their education and learning environment.
