Featured: what people still come here looking for
This was the "featured" shelf of the old Don Express marketplace — the rotating front-page selection. The storefront is offline, so instead of a shelf of listings, here is the honest version: the things visitors still arrive here searching for, and the maintained guide for each one.
Nothing on this page is for sale. Every link goes to a buying guide about sourcing that kind of product directly from the manufacturers who made it.
The category guides
Solar products
The single most-requested category: panels, power stations, inverters and charge controllers — how to read a spec sheet, catch invented wattage and capacity ratings, and ship lithium legally.
Machines & equipment
Laser cutters and engravers, CNC, packing and sewing machines, pumps and generators: voltage and phase, honest power ratings, certification, crated freight and spare parts.
Motor & vehicle spare parts
Buying by part number, genuine vs OEM vs aftermarket, counterfeit safety parts, approval marks for brakes and lighting, and supplier qualification.
Jewelry & watches
Metal stamps and plating microns, moissanite vs lab-grown vs CZ, movements and water ratings, and the smartwatch claims that get sellers in trouble.
Clothing & apparel
Where to buy, minimum orders and private label, the sizing and quality traps, labelling and duties.
General retail goods
The long tail — chargers and cables, car care, adhesives, beauty tools, hair, kitchen gadgets, refurbished phones: variant traps, compliance per family, consolidation freight.
The specific products people still ask about
Drawn from what visitors actually request, these are the product families with the most traffic to their old listings — and where to read about sourcing them:
- Solar panels, portable power stations and hybrid inverters — the busiest of all. Start with the solar guide, particularly the sections on area-versus-wattage maths and battery weight maths.
- Cordless bag sewing and sack-closing machines — the most-requested single item in the archive. See machines & equipment for duty cycle, battery mounts and spare parts.
- Laser engravers and fiber laser cutters — diode, CO2 and fiber are three different machines; the comparison table in the machines guide covers which one cuts what.
- Water pumps, diaphragm and submersible — read the performance curve, not the maximum figures: machines guide.
- Hub bearings, fuel pumps, AC compressors and automotive bulbs — buy by part number and check approval marks: motor spare parts guide.
- Smartwatches — the clone segment and the health-sensor claims are both traps: jewelry & watches guide.
- 925 silver and moissanite jewelry — stamps, plating thickness and stone disclosure: jewelry & watches guide.
- USB-C cables, chargers and refurbished phones — wattage claims, certification and grading language: general retail goods guide.
- Barcode scanners and handheld PDAs — scan engines, Android support and radio paperwork: machines guide.
And the rest of the site
Most people arriving here aren't buying at all — they're tracking something, or planning a move. The other maintained guides:
- Track a package from China — carrier formats, realistic timelines, and what the silent gaps mean.
- Shipping & sourcing — freight channels, incoterms, supplier vetting and inspections.
- China's wholesale markets — Yiwu, Guangzhou, Huaqiangbei and the specialty clusters behind every category above.
- Study in China, living in China, working in China, visas and document notarization.
