Shacha broth is the heart of the bowl
Shacha noodles are a common noodle soup in Xiamen. Shacha sauce gives the broth an orange-red colour, with peanuts and marine ingredients such as dried shrimp contributing to its flavour; chilli and seasonings add a little spice. The 'cha', or tea, in the name does not mean tea leaves are added to the soup. 'Satay noodles' on English menus refers to this local dish with roots in Southeast Asian food traditions.
Broths vary in richness, sweetness, saltiness and heat, so colour alone will not tell you how spicy a bowl is. To understand the dish, try the broth before the noodles and toppings. Peanuts, dried shrimp and other ingredients may already be in the sauce or stock. Removing visible seafood does not remove seafood ingredients, and asking for no added chilli does not mean a separate broth will be made.

Oiled wheat noodles, bean sprouts and chosen additions
A common method is to blanch oiled wheat noodles and bean sprouts, then add the chosen ingredients and shacha broth. The noodles are springy and the sprouts crisp. Fried tofu and other bean products soak up the broth, offering textures quite different from sliced meat, pork liver, squid or shrimp. Ingredients vary by vendor and daily availability; not everything in a photograph is part of a fixed recipe.
For a first order, consider two or three familiar ingredients, such as a bean product with one meat or seafood option, then decide whether you need more. This is an ordering suggestion, not a standard set meal. If you do not eat offal, state specifics such as 'no pork liver, kidney or intestines'. Simply saying 'no meat' may not explain your restrictions on seafood, meat stock or meat and fish balls.

A meal in a snack shop, with other dishes if wanted
Shacha noodles can be a meal on their own and are also served in shops selling other southern Fujian snacks. More additions may mean a larger portion and a higher price. Ask what the basic noodles include and how extras are priced before ordering more dishes. There is no single price list for the whole city; prices on old signs or in old travel accounts are not current quotations.
The noodles, soup and toppings have different temperatures and textures, which are easier to appreciate while the bowl is hot. If you also want an oyster omelette or other fried snacks, choose fewer additions first to avoid ordering several full main dishes. Companions can choose different toppings to compare, without pursuing an unverified 'best in the city' ranking.

Check allergens and dietary restrictions first
Shacha sauce commonly contains peanuts, dried shrimp and chilli, while the noodles are usually made from wheat. Bean products, seafood and meat bring their own dietary restrictions. Visitors allergic to peanuts, crustaceans, soy or wheat should ask about the sauce, stock, noodles and additions, rather than only the visible toppings. Rely on the recipe details the vendor can actually confirm.
If the vendor cannot explain the broth or sauce ingredients, anyone with strict allergy restrictions should choose food whose ingredients can be confirmed. Vegetarians should not assume a bowl with only bean sprouts and tofu is vegetarian. The photographs show bowls and shopfronts from different years to explain the dish and ordering setting; they do not establish those shops' current menus, prices or opening arrangements.
