A very old Hong Kong show with no English subs, which I'm afraid I wouldn't recommend even if you were into any of those things. XD It's called 天降财神 | The Superpower. Chow Yun-Fat as a very earnest and confused alien was great, but sadly even he and Tony Leung together could not save the plot...

I enjoyed all the sci-fi vocab, though! Another one I loved was meteor shower: 流星雨. Also, alien babies came from test tubes: 试管!
