Perhaps you should try some spelling variations:
training course » training courses
training risk » trading risk, training crisis, defining risk
training cost » training costs, training courses
equal credit » dual credit, equity credit, rural credit
yang dang » yang yang, yang guang, yang liang
hong shu » cong shu, tong shui, wong shiu
y equal » _ equal, 6 equal, e equals
dang y » dang ly, yang y

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

• Performing a fuzzy search may retrieve terms with similar spellings: yang dang y equal credit ((((training risk) OR (training cost))) or (training course)) hong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yang dang y equal credit ((((training risk) OR (training cost))) OR (training course)) hong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang dang y equal credit ((((training risk) OR (training cost))) or (training course)) hong shu ;*".
