The original Japanese uses hanzi with katakana, the romanisation uses the katakana reading to reflect how the singer pronounces it so you can sing along (with the exception of the title), while the English translation uses Pinyin. Hope that makes sense.
The title is a Chinese proverb.
Some of kanji have creative readings (onna/hito) and this isn't a mistake on my part. Except when it is. I'm now able to check this song against the CD, but that doesn't mean it's any more accurate.

"Yes My Lord" (Sebastian's Song) is here.

Lau's Song
"Shì Shàng Méi Yǒu Néng Zhì Hòu Huǐ De Yào"

Utsuru keshiki wo nagame tsutsu   uta to sake ni yoishirete   deau hito ni na wo kikeba   kokoro odoru
(Douse kono yo wa)   Hakanai yume   (Kiete shimau wa)   Utakata nara
Nee   gense demo raise demo nandemo   tanoshimasete

Kinou, kyou, asu   toki wa matanai   dato sureba kakete goran yo naze nara
Pai ni kakureta DORA wo TSUMOru ka　Dareka ni TSUMOrareru ka no   Sadame wa kami nomi zo shiru kara

SHII SHAN MEI YOU NAN JII HOU HOI DA YAO   SHII SHAN MEI YOU NAN JII HOU HOI DA YAO   SHII SHAN MEI YOU NAN JII HOU HOI DA YAO
Koukai no kusuri   (Aru naraba   ima sugu ni kawasete)

TON NAN SHAA PEI doko e ikedomo kanarazu shiawasegaru   tabun ne
Wagakuni ni wa konna oshie ga aru kara oshiete ageru   wasureta

(Semete hitotsu dake   oshiete hoshii)   Saa ne doushiyou ka
(Oshiete ijiwaru   onegai dakara)   Ja yoku kiite?
(RA RA RA RA RA...)

Inishie yori...   Aa kyoku owacchatta

   

Lau's Song
"Shì Shàng Méi Yǒu Néng Zhì Hòu Huǐ De Yào" (There's No Medicine For Regret In All The World)

Watching the shifting landscape   Getting drunk on liquor and music When I hear the names of the women I meet   My heart dances
(In any case this world is just)   A fleeting dream   (It'll vanish)   Because it's ephemeral
So hey   Now or in the future or whenever   Let's enjoy life

Yesterday, today, tomorrow   Time won't wait   If you understand this, spend your time well
You never know if you hold the Dragon in Mah-jongg   Or if someone else holds that tile   Because only God understands fate

Shì shàng méi yǒu néng zhì hòu huǐ de yào   Shì shàng méi yǒu néng zhì hòu huǐ de yào   Shì shàng méi yǒu néng zhì hòu huǐ de yào
The remedy for regret (If you see it   buy it immediately)

In the four corners of the world, across dong nan xi bei   it's no crime to seek pleasure wherever you go   I think
These are the teachings of our country   Let us teach you   I forget

(If nothing else   we want to teach you this one thing)   So, what should we do?
(We will teach you   because it's our wish)   Will you listen closely?
(La la la la la...)

From ancient times....   Oh, song's over.

   


劉　歌唱曲
「世上没有能治后悔的药」

移る景色を眺めつつ　歌と酒に酔いしれて　出会う女に名を訊けば　心躍る
（どうせこの世は）儚い夢（消えてしまうわ）うたかたなら
ねぇ　現世でも来世でも何でも　楽しませて

昨日、今日、明日　時は待たない　だとすれば掛けてご覧よ　何故なら
牌に隠れたドラをツモるか　誰かにツモられるかの　運命は神のみぞ知るから

世上没有能治后悔的药（シーシャンメイヨウナンジィホウホィダヤォ）
世上没有能治后悔的药（シーシャンメイヨウナンジィホウホィダヤォ）
世上没有能治后悔的药（シーシャンメイヨウナンジィホウホィダヤォ）
後悔の薬（あるならば　今すぐに買わせて）

東南西北（トンナンシャーペイ）どこへ行けども必ず幸せがる　多分ね
我が国にはこんな教えがあるから　教えてあげる　忘れた

（せめて一つだけ　教えてほしい）　さあねどうしようか
（教えて意地悪　お願いだから）　じゃよく聞いて？
（ラララララ…）

古より…ああ曲終わっちゃった
