Perhaps you should try some spelling variations:
scaling point » starting point, boiling point, scaling down
when scaling » when dealing, when starting, when setting
wan yanling » wang yanling, wang yangming, wang danning
last when » art when, best when, last why
point did » point de, point dtp
yang xi » yang yi, yang jui
tang » tan, lang, wang

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wan yanling ((tang li) OR (((yang xi) OR (yang di)))) last when scaling point did ;~.
• Adding a wildcard symbol may retrieve word variants: wan yanling ((tang li) or (((yang xi) or (yang di)))) last when scaling point did ;*.
