Just Search in English
About 90% of the time, a Taobao search with an English word will hit the mark. Many products on Taobao are labeled with both English and Chinese names. And a growing number are labeled with English names alone.
Use the English Name to Find the Chinese Name
You can also use an English-language search to help determine the Chinese name. This will often help you find more products so you have more choices.
For example, a search for “drill” comes up with less than 200 results. But two of the results give a clue to the Chinese name. We can copy/paste 电钻 back into Taobao to get over 7000 results.
