Perhaps you should try some spelling variations:
across sectional » cross sectional, cross section, cross sections
working across » working class, workers across
sectional site » sectional units, sectional data, sectional case
late working » care working, face working, life working
fan xing » fan ying, fan xibo, tan xin
dort bin » dort hin, dong bin, dort von
dort ii » dort hin
sin » sign, sind, skin

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: fan xing late working across sectional site ((((dort bin) OR (dort ii))) OR (dong sin)) ;~.
• Adding a wildcard symbol may retrieve word variants: fan xing late working across sectional site ((((dort bin) or (dort ii))) or (dong sin)) ;*.
