好奇Chakara是什么东西，还专门科研了wikipedia，说是个印度语，Chakara is a Malayalam word used to describe a peculiar marine phenomenon in which a large number of fish and prawns throng together during a particular season as a result of mud bank formations. This rare phenomenon is observed only along the coastal waters of the Indian state of Kerala, especially around the coast of Purakkad[1] and in South America, where it has proved to be a boon for the local fisherfolk. 楼主，你是说这戒指放水里能引来好多鱼么？
