Discuss your needs with medical professionals before departure, bring necessary medications, and prepare brief Chinese instructions for restaurants and hotels.
Make the information specific
Specify specific ingredients, how much to avoid, and whether you care about cross-contact. Busy kitchens are harder to carry out long, general explanations.
Prioritize support over taking risks
Ask the staff for the latest local advice, prioritize places where communication is clear, and prepare simple backup meals on your move day.
