There has been commentary in the past for both Zhang Jing Yi and Chen Zhe Yuan that both have modern faces and thus look out of place in period dramas. Of course both have done period dramas before to varying degrees of success and are now teaming up for the recently started filming drama Chasing Dreams (Meng Hua Ting 梦花廷) based on Flower in Novoland. She does have some dangly bit in her hairpiece but overall the whole look really suits her, she is way prettier here than in her last period drama Blossoms in Adversity. As for him, less is always more and a general wuxia warrior/prince look suits him very as well.
