Jian debuted with LUNARSOLAR only about a year ago yet she has already gained titles such as 'singing fairy' even before debuting.

In 2019, while she was a trainee, she posted a vocal cover of HYNN's song 'The Lonely Bloom Stands Alone' which is noted as a hard song to sing. The song went viral in Korea with over 2M views on Facebook. Most comments were shocked that someone who is so pretty could be so good at singing as well.

Due to her outstanding vocal skills and her viral cover, she was invited to Mnet's show 'I Can See Your Voice 7' in March 2020. She performed a cover of Ben's 'Like A Dream' and told a bit of her story about wanting to be a singer and how she even thought about giving up her dream. She shocked the judge panel, which included idols such as Super Junior's Shindong and Lovelyz's Mijoo, with her amazing vocals. After her appearance on the show, she gained titles such as 'cover fairy,' 'singing fairy' and more, as well as trending on Naver search.

In November 2020, only two months after debuting in LUNARSOLAR, she was invited to perform at Immortal Songs with her labelmate Lee Sejoon from Yurisangja. They performed a cover of Kim Hyeonchul & Lee Sora's 'The Blue in You' where she showed off her amazing vocals once again as a rookie. Jian and LUNARSOLAR both trended on Naver after the performance aired on KBS. Lee Sejoon is also known for his vocals and being part of duo, Yurisangja, which has been active since 1997. Yurisangja has also helped LUNARSOLAR with training their vocals.

Another outstanding cover from Jian would be her cover of Hwang In Wook's 'I Think I'm Drunk,' which has more views on YouTube than the original song. She really proved herself to have an amazing technique and great control over her voice while showing off both a high and low range. No wonder she can be considered the best 4th generation vocalist!
