Dear Mr.Lee, Thank you for your advice. The neighbour does not listen to us and persist in hanging up the pakua saying that it is for his family good. After observing, his pakua is actually hanging at the main door and infront ishis metal grill door whick at certain angle block direct sight of the pakua from our door. Will hanging potted plants outside our door helps or hanging wind chime helps in this case. ThankYou Regards See
