Four members of a grassroots movement campaigning to curb corruption among Chinese officials and boost fairness in education are standing trial on charges of disrupting public order, a day after the group's founder was sentenced to prison.

The prosecutions against members of the New Citizens Movement who participated in small public rallies reflect the leadership's wariness of any group that can generate enough momentum to challenge its one-party rule.

Group founder Xu Zhiyong was sentenced Sunday to four years in prison.

The four who appeared in court Monday were Zhang Baocheng, Yuan Dong, Ding Jiaxi and Li Wei. The lawyer for two of the men, Chen Jiangang, said they had had "no chance to express their views, their opinions" during the hearing.
