First of all, I think your question may not be accurate. According to common sense, county committees generally have XianWeiBan. Below the county office, there are secretarial section, administrative section, information section, political research room, supervision room, confidential bureau, secrecy bureau and other departments. I haven't heard of any county party committee directly setting up a secretariat.

According to the information I checked on the Internet, the director of Xianju County Xianweiban is Wang Xiaoxing, and the deputy director of Xianweiban is Wang Jinbao and Wu Weijun. I don't know if there is any substitution.
