1. What level of the product are you looking at?
Choose one ordinary product function to follow through the market: supplying power, capturing sound or connecting a device. Ask whether the item in front of you is a component, a module, an accessory or a finished product. SEG describes its electronics-market business as covering components, computers and accessories, communications products and wearables. That range makes these distinctions a useful starting point; it does not establish the stock of a particular seller.
For a student group, sketch a simple chain from a part to a finished use. Mark any connections you are assuming. The exercise should help generate questions for a later conversation, without pretending that every stage of a supply chain is visible from a counter.
2. Which specification changes whether it fits?
Two items can look similar while serving different requirements. Ask which specifications define the intended use and where those details are documented. Depending on the item, a relevant question might concern its dimensions, interface, power requirements or supported software. Keep the enquiry connected to a real application or a clearly labelled classroom example.
Record the model or version being discussed. If a seller offers an alternative, ask what changed and what would need to be checked before treating it as equivalent. This gives a business or engineering cohort a concrete way to discuss why a product description needs more than a photograph.
3. Who does what in getting it to the customer?
Ask the seller which role they perform: retail sales, distribution, assembly, customisation or another service. Record the answer as their description until independently verified. A market visit can reveal useful questions about relationships, but a conversation at a stall does not establish factory ownership or manufacturing capability.
A group can compare the roles described by different businesses without ranking their quality. Ask permission before conducting an interview and avoid blocking normal trading. A short, well-prepared question is more respectful and more useful than expecting every merchant to deliver a presentation.
4. What changes between a sample and a repeat order?
Ask what information would be needed to discuss a later order: the exact specification, quantity, version and intended destination. Explore how a buyer could recognise whether a subsequent unit matches the sample. Treat statements about availability or lead time as dated answers which would need reconfirmation in a purchasing process.
For a learning task, write down the evidence a buyer would request next. You do not need to buy something to make the exercise useful. Product testing, supplier checks and transaction decisions require their own work beyond the visit.
5. What support does the product depend on?
Ask what happens after the product leaves the market. Does it require an account, an application, setup assistance or replacement parts? Who would answer a support question? If the intended use is outside China, note what would need to be checked for that destination. Do not infer local compatibility or approval from the fact that a product is on display.
6. What did this visit actually establish?
Finish with a one-page map of the product, the roles described and the uncertainties that remain. Separate items you handled, specifications you read and statements you heard. This original field-question framework is intended for observation and discussion. It is not a sourcing endorsement, a purchasing recommendation or a claim that La Roja has audited the businesses encountered. The most useful result may be a better next question.
