Which job site is good for companies in Fujian? (pump valve industry)

I am doing personnel, in the company has been responsible for recruitment. Have been using the Straits Talent Network, general jobs or administrative/comprehensive management positions okay, now the company wants to recruit technical and valve sales staff, feel obviously not enough. 51JOB four years ago, spent more than eight thousand silver, then felt the effect in Fujian this side of the Straits Talent Network is not as good as the interface is not good to use the other, such as China Talent, Wisdom Link Recruitment Network, JOB88 and so on have not used, I do not know what the effect is? 0?2 another two days with the intention of cooperation with Xiamen Talent Network, but I looked on their website, three days, we in Fujian side of the pump and valve industry in their management jobs released less than 10 information, I'm worried about spending the money it is still can not recruit people. So here I also hope that there are hotels HR colleagues to point out a two, revealing the recruitment effect of this site compared to how? Hee hee. At the same time, I also hope that there are engaged in the pump and valve industry management of technical positions of friends can reply: generally you look for work, will prefer which job site?
