I was able to find out some of the answers for the Riddle Paper questions, and I thought it would be fair to post them here as well.
Not sure if anyone will ever need this thread, tho, considering that I left the pictures in Chinese and in order to find the answer you are looking for you have to search through all of them, but still, maybe someone will need this someday.
These are not all the answers, I've tried to find more but I can't speak or read Chinese so I could only give random answers or try to translate it on the internet if I was lucky enough to hit the right characters.
Feel free to send me or comment more answers if you find any! I'll update this thread if I ever find more answers or questions.
