Leizhou has been rich in pearls since ancient times. "Lingnan sees the record" records: "The rumor is thunder and pregnant, looking at the moon and the tires." Liusha Nanzhu is famous at home and abroad. Its roundness is dignified and crystal clear, which is favored by the domestic and international jewelry circles. Therefore, it is said that “Dongzhu is not as good as Xizhu, and Xizhu is not as good as Nanzhu”.
