The four Conversations field guides as handouts, for a small group, a Sunday school class, or your own pocket before Qing Ming.
Each handout is the full field guide: what you will see, the words your friend will use, where Christian belief and the practice meet and part, and questions you could actually ask.
They are best read in order. Qing Ming introduces the vocabulary the other three reuse, and the book these guides come from says to approach funerals last, because that is where a careless word does the most harm.
Who do you know that keeps one of these festivals, and what would you want to ask them?
