Как сказать по-русски "I like the coral reefs" "I don't like the pollution" ? Thank you in advance :)

Any cultural shock you have experienced when travelling to a different place (or places)?

Could you recommend me any songs, movies or series in Russian? (trying to improve my listening) Thank you in advance :)

How can I say "thank you for your help and your patience" in Russian? Thank you in advance :)

What motivates you to learn the language (or languages) that you are learning right now?

My motivation to learn Korean is because I like the culture of South Korea, the Korean alphabet and I would like to travel to South Korea some day in the future.

My motivation to learn Russian is because I like the sound of that language and the Cyrillic alphabet seems very interesting to me, I would also like to travel to many Russian-speaking nations some day.

How can I say "Good luck" in Korean in a polite way and "good luck ' in Korean in a friendly way? Thank you in advance :)
