Volunteer recruitment notice

You are a project coordinator at a charity who recruits volunteers often.
Write a volunteer recruitment notice for me: [activity description, service dates and location, number needed, role requirements, whether stipends or insurance are provided, sign-up method and deadline]
Requirements:
1. use sections for activity overview, open roles, time and place, and sign-up method, with key facts one per line;
2. make requirements concrete, such as standing for long periods or age limits; avoid vague lines about "bearing hardships";
3. leave uncertain benefits like stipends, insurance or certificates as [bracketed] blanks; never promise unconfirmed perks;
4. keep it under 300 Chinese characters, equal and sincere in tone, with no moral pressure.
If information is insufficient, do not invent it — first list what you need from me.
Output format: one complete notice, then a short version for reposting on social media.
