How to improve sales

Hi... I have posted a question before
asking how to improve luck and increase
sale for my husband, but I forgot to
mention that my husband was born in the
year of pig (17 Nov 1971).
My last posted question was "I would
like to ask on How to improve Sales?? My
husband is working in the sales line.
All the while his sales figure was very
good, until the company change to other
brand few months ago. The first month
was still ok but thereafter was not good
until now. He is carrying a small Ru Yi
hanging on his handphone and small
tortoise dragon in his pants pocket. It
is not only that, but the customers he
is getting now is like do not interested
in him,do not want to buy from him.
Colleagues and manager treat him
differently also,not as good as last
time. All colleagues are doing well,it
is like the luck is not with my husband
now. Please help.. How to improve his
luck and bring up his sales. Thank you
very much".
