Chang Ching, known professionally as Ro Na, is a Taiwanese singer, dancer, and former member of ILY:1 (아일리원). She graduated from Juang Jing International Vocational High School.

Before debuting, she spent several years as a trainee at TPE48. The group was formed in mid-2015 as the sixth international sister group of AKB48. However, many issues delayed their official debut, which did not happen until February 2018, when 40 girls (13 members and 27 trainees) were finally selected.

However, by June of that year, TPE48 Entertainment (熙曜娛樂) faced financial problems, and AKS decided to cancel the joint venture and license agreement with TPE48 and took sole control of the group, rebranding it as AKB48 Team TP the following month. As she had virtually no chance of performing, she decided to move to South Korea.

She finally made her debut in April 2022 as ILY:1's sub-vocalist with their first single "Love in Bloom". They are managed by FC ENM (에프씨이엔엠).

In June 2025, the group members posted a message thanking their fans and announcing their disbandment.
