What is "vivibear"

Weiwei Zhang is a Chinese-Swedish author who writes under the pseudonym vivibear. Her stories include romance novels and time-traveling series for young adults, all published in Chinese. To date, all sixteen novels she wrote were believed to be found with various degrees of plagiarism, and the discovery was widely reported by Chinese media.
