Mandarin Version: 滄海一聲笑 [A laugh heard in the vast sea / Swordman Theme] - Sam Hui 許冠傑 {Cantonese 94}

滄海一聲笑，
A laugh heard in the vast sea(in a vast sea, a single human voice is heard, very dramatic scenario for a character introduction)

滔滔兩岸潮，
Tide rise and fall from both side of the shores(tidal movement has been going on for eon, thus make a single human life seem  Immaterial)

浮沉隨浪只記今朝。
drifting with the  waves, only care about today (here and now)

蒼天笑，紛紛世上潮，
Heaven laugh, this hectic mortal world ( laughing at human's pointlessly struggle against each other in the eyes of the immortal sky)

誰負誰勝出天知曉。
Heaven already knew who win and who lose 

江山笑，煙雨遙，
River and mountains laugh (at the human of course), misty rain far away.(rain don't care)

濤浪淘盡紅塵俗世幾多驕。
Tides came and tides went, (time gone by) carried away  how many great men and heroes from this mortal world with it?(countless)

清風笑，竟惹寂寥，
cool wind laugh, bring fore loneliness.

豪情還剩了一襟晚照。
All that youthful unyielding  spirit in the world,  would eventually be dimly Illuminated by only the sunset light.

蒼生笑，不再寂寥，
(hear)The common people laugh, (the hero)no longer feel lonely.

豪情仍在痴痴笑笑。啦
……(my )unyielding  spirit is still alive (I) laugh too. 

P.s
Original on the web: 濤浪淘盡紅塵俗世幾多「嬌」but it should be 「驕」
People call 成吉思汗(Genghis Khan)「一代天嬌」「天驕」as in 「天之驕子」(Favored son of the Heaven).
幾多驕 here mean how many great men and heroes
紅塵俗世= mortal world
