Perhaps you should try some spelling variations:
when scaling » when dealing, when starting, when setting
huang cheng » huang chang, hong cheng, huang weng
scaling how » scaling down, stealing how, scaling law
long days » long day's, longer days, long way
yang jun » yang jui, pang jun, yang jin
wai yan » wang yan, wei yang

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: ((wai yan) OR (huang cheng)) ((yang judy) OR (yang jun)) when scaling how long days ;~.
• Adding a wildcard symbol may retrieve word variants: ((wai yan) or (huang cheng)) ((yang judy) or (yang jun)) when scaling how long days ;*.
