Perhaps you should try some spelling variations:
sharing oil » sharing our, sharing his, sharing covid
sharing big » sharing bad, sharing his, sharing best
wang ban » wang yan, wang dan, wang yang
can post » can cost, can lost, can past
can cash » a cash
can dai » can ai, can draw, bang dai
ban zi » ban ji, yan zi

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: wang ban zi ((can post) OR (((can cash) OR (do cash)))) ((sharing oil) OR (sharing big)) can dai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ban zi ((can post) or (((can cash) or (do cash)))) ((sharing oil) OR (sharing big)) can dai ;~".
• Adding a wildcard symbol may retrieve word variants: wang ban zi ((can post) or (((can cash) or (do cash)))) ((sharing oil) OR (sharing big)) can dai ;*.
