1. Match the page to the job
| What you are trying to do | Use this page | What to check |
|---|---|---|
| Compare product rows | The independent spreadsheet guide | Whether the row shows a useful source, relevant photos, measurements, price context, and a realistic weight assumption. |
| Inspect the original item | The seller or marketplace source page | Whether the title, image, option, and visible price still describe the same item. |
| Check fit, photos, or likely cost | The relevant evidence guide on this site | Use the same measuring method and assumptions across every item you compare. |
| Manage an account, order, or shipment | The current official Welisen service | Use the channel attached to the real account or parcel, not an unrelated form or guide. |
A product row can help you decide what deserves a closer look. It cannot confirm current stock, seller identity, product quality, service availability, or delivery cost. Those answers must come from the relevant source or official service.
2. Use the official service for operational questions
An independent guide cannot see your account, warehouse record, parcel measurement, route options, or payment status. When the answer depends on current service rules or personal order data, go directly to the official website or app.
| If you need | What to confirm in the official channel |
|---|---|
| Warehouse or warehouse address | The current address, recipient format, account instructions and whether the warehouse accepts that item type. |
| Package or parcel consolidation | Eligibility, storage limits, packing choices, measured parcel data and current fees. |
| Repacking | Which packaging may be removed, what protection remains and how the change can affect chargeable weight. |
| Shipping or international shipping | Available routes, destination coverage, restricted items, transit estimates and current policies. |
| Shipping rates or shipping calculator | The currency, destination, weight basis, dimensions, surcharges and whether the result is only an estimate. |
| Tracking, app or customer service | The status and support information attached to the real account, order or parcel. |
This site cannot access a login, locate a parcel, issue a quote, or speak for official support. Keep account numbers, addresses, payment details, and tracking information out of unrelated pages and public forms.
3. Use source pages for product details
Taobao, Tmall, Weidian, Pinduoduo, and JD.com usually lead to retail listings. A 1688 page may use wholesale quantities, option-dependent prices, or a starting price that is not the price of the item shown. A Yupoo page may be a photo album without the transaction details needed to compare cost or availability.
Preserve the original URL before opening a converted or redirected link. Then compare the item title, main image, selectable option, and visible price with the row you started from. The source-link guide explains what each page can and cannot show.
A converted link is a route, not a verification. If the destination changes the product, option, seller, or price context, return to the original source and resolve the mismatch before saving the item.
4. Look for the evidence missing from the row
QC and item-specific photos
Confirm that item-specific photos belong to the same item and option, then inspect the angles that matter for the category. Shoes need a profile, outsole, heel, and size evidence; bags need scale, closures, interior, and hardware. Use the QC photo guide, and never treat the existence of photos as a quality guarantee.
Fit and measurement
A size chart is a starting point, not an answer by itself. Footwear comparisons benefit from insole length; clothing comparisons need garment measurements taken in a consistent way. Compare the same unit and measuring method with an item you already use, following the measurement guide.
Weight and the whole cost
Actual weight, packed weight, and dimensional weight are related but different inputs. Any estimate is only as useful as its destination, route, dimensions, and packing assumptions. Compare a light, expected, and heavier scenario when the row is incomplete.
For a realistic total, include the item price, domestic delivery, service or handling costs, packing, international shipping, payment conversion, and possible destination charges. Confirm fees, restricted-item rules, storage limits, and return options through the current official terms that apply to the actual item and destination.
5. Handle reviews and safety claims carefully
One review may describe a single user, route, date, or product type. It cannot settle every question about a service or listing. Check the current official identity and policies, protect account credentials, compare recent independent experiences, and use a payment method whose terms you understand.
For product discovery, apply a smaller test: does the row show the same item, a useful original source, category-specific photos, comparable measurements, a plausible price and a weight assumption? If not, remove it before the uncertainty becomes a purchase problem.
Boundary: Welisen.org does not sell, verify, purchase, store, consolidate, repack, ship, or track products. It helps readers identify missing evidence before they continue on a third-party directory, seller page, or official service.
