Google chrome has automatic translate that does all the work for you.
On top of that, google translate app allows you to highlight key text for translation, and more importantly; copy/paste.
On top of that, YAJ has some of the most specific subcategories for search of any auction and/or retail site I’ve ever seen.
If you can’t narrow your search with all three of those tools, you are lazy, unwilling to ‘work’ to help yourself, and borderline useless.

Also, there are no secret keywords to search that unlock endless auctions of rare parts and good deals. Those days are long over.
If you want to find rare parts or good deals, just like anywhere else, you have to have some patience, a little luck, and actually spend some time hunting like everyone else.

If people are reluctant to help you it’s because YAJ is slim pickings these days. No one wants to spoon feed links to the promising auctions they have found because that just drums up more competition for themselves.
Either that, or you’re one of the borderline useless people as mentioned above and chances are conversation with you is generally irritating.
