Princess Huanzhu was a very famous online novel written by Qiong Yao. Although she had passed away, her novels were still loved by readers. As for whether or not he would shoot Princess Pearl's fourth movie, the answer was no. Although Qiong Yao's novel copyright had expired, her works were still popular. If a film company decided to film the fourth part of Princess Pearl, they would need to re-obtain Qiong Yao's authorization and carry out sufficient copyright negotiations and preparations. Therefore, we can't be sure if we will shoot Princess Huanzhu's fourth film. We can only hope that Qiong Yao's works will continue to be protected and explored.
