I dont think you should.
Canada joined the korea war against China.
Your compartriots sacrificed blood to protect our country at then, your grand grand father probably was one of them. They protected your family from being killed.
You are immigrant now for some reasons, but you are still chinese. i dont think you should be showing respect to someone who had killed "your grand grand father".
Even canadians at then lost their lives and family members for joining this idoit war. Further more, we pray for peace for the whole world.
Once again, I feel sick for those chinese who wear it.
