Beyond local noodles, soup dumplings, fish and stir-fries, international travelers should clarify allergens, stock, sauces, shared equipment and religious or vegetarian requirements item by item.
Write the need in Chinese
Prepare an offline card naming each forbidden ingredient, the consequence of exposure and whether shared oil or cookware is acceptable. 'Vegetarian' does not specify eggs, dairy, alliums, fish sauce or animal stock; 'allergy' does not identify the allergen.
The municipal food directory introduces local dishes but is not an allergy certification. Dumplings, fish, barbecue and rice-noodle seasoning must be checked restaurant by restaurant.
Ask four questions
Confirm the main ingredient, stock or sauce, shared fryer or cookware, and whether separate preparation is possible. For severe allergy, state that trace contact is unsafe. Show translated text for staff to confirm rather than only playing audio.
Carry safe packaged snacks and water. If a night market, rural stop or busy kitchen cannot verify ingredients, choose a clearer option or do not order.
A guide can help, not guarantee
A multilingual guide may translate, call ahead and review a menu, but cannot replace medical advice or guarantee zero cross-contact. Carry physician-recommended medication and a Chinese emergency note for severe allergy.
For a rural private-car day, prepare backup food in the city. A driver should not substitute an unverified restaurant recommendation for a safety check.
