Dear, I am trying to contact Miss Sharon (export manager) on ysexport@ysweb.com but I am not having success. I need informations about musical mechanism and I bought in 2005 from Yunsheng a small trial order. Now I need to do a new order but it has been dificult because I do not have reply to my e-mails. Would you please contact me? Sincerely, Celso Mamede. bakana@pobox.com
