It could be 巴布亚硝水母in Chinese, commonly called the spotted jelly or the lagoon jelly, which is a jellyfish species living in the Indian and Pacific oceans.
I support the comment of Monalisha. It is Mastigias sp. Please check the species identity. Some are identified this species as Mastigias papua.
Experts in the taxonomy of jellyfish says that no chance for Mastigia papua in India. So you may check the characters. If you have any help for identification please contacts me
