1. Questions are encouraged, but titles should summarize the core issue (e.g., "[Help] How to buy SIM card at Beijing T3?"). Avoid zero-information titles like "Urgent! Help me!"
2. Include your nationality (affects visa/payment answers), current city, and attempted solutions for precise responses.
3. Answerers must remain patient and friendly. Mocking beginners or posting belittling comments like "How do you not know this?" is prohibited. Community tone is everyone's responsibility.
4. Moderators regularly compile high-frequency questions into "FAQ Megathreads"—check the pinned posts first.
