Na Ying
After recovering from his depression, two years later, Yang Kun released his fourth release, "Cowboy", under Huayi Brothers. This album was considered by the singer as introspective, with all the songs talking about his recent life and how he tried to find himself. This album was highly promoted by his new company, and many concerts and promotional events for this release were made. During this time, he became friends with new collaborators such as Na Ying and David Huang.
