your chain » your brain, your claim, your channel
kongo your » kong your
wang yuan » wang yuhan, wang yan, fang yuan
your gain » you gain, your brain, poor gain

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yuan change ((your gain) OR (your chain)) yang dia kongo your ;~".
• Adding a wildcard symbol may retrieve word variants: wang yuan change ((your gain) OR (your chain)) yang dia kongo your ;*.
