During this period, many Cantopop singers from Hong Kong such as the "Four Heavenly Kings" - Aaron Kwok, Leon Lai, Andy Lau and Jacky Cheung - also began to dominate Mandopop. One of the best-selling Mandarin albums was the 1993 album "The Goodbye Kiss" by Jacky Cheung which sold over 1 million in Taiwan and 4 million in total Asia-wide. Nonetheless, Taiwan has their own popular singers such as Stella Chang, Sky Wu, Wakin Chau (formerly Emil Chau) and Jeff Chang. Independent labels such as Rock Records began to establish themselves in this period as some of the most influential labels. Towards the end of the 90s, other singers such as Leehom Wang and David Tao became popular, and some also began to perform in the R&B and/or hip-hop genres.
