Ko Cheng, or La Khai, was a king of Champa from 1390–1400. This general of Che Bong Nga's led the retreat back to Champa in 1390, following the death of Che Bong Nga by a musketry salvo. Back in Champa, he declared himself king, usurping the two sons of Che Bong Nga, Che Ma-no Da-nan and Che San-no.

During his reign, he abandoned most of the territory won by his predecessor, Che Bong Nga.

羅皚（；？ - 1400年），即僧伽跋摩六世（Simhavarman VI），《明史》作閣勝，是占城第十四王朝的建立者，1390年至1400年在位。

羅皚原為占城國大將。1390年（洪武二十三年），占城王阿答阿者在與大越陳朝的交戰中陣亡，羅皚趁機歸國奪取王位。阿答阿者的兒子制麻奴㐌難、制山拏擔心被殺，出奔大越避難。

1391年（洪武二十四年），羅皚遣使向明朝朝貢。明太祖誤以為羅皚殺死阿答阿者篡位，惡其悖逆，退還貢品，不准入貢。直到1397年（洪武三十年），占城才再次向明朝貢。
