^I can tell you what the Chinese lyrics were.
如果星球不下雨,那么我们也找不到相爱的理由
我们的使命应该是努力,把珍贵的一切交给未来
没有了陆地,无法成为动人美丽的星球
我们大声唱,拼命地唱出我的爱
For people who don't understand Chinese:
If it doesn't rain in this world, then we would be unable to find a reason to love each other
Being hardworking should be our mission, entrusting all that is precious to us to the future
If there were no lands, this world cannot become beautiful
Let us sing loudly, singing out our love.
Yup.
