later liu appoint an ex subordinate of han xin to be governor. this general visit han xin before he left and han xin arranged with this general to revolt. han xin told the general that liu bang will lead the punitive expediation himself and han xin will stage a revolt in the capital once liu bang forces engage the rebels. but news of han xin involvement reach lu zhi and both she and xiao he plotted to capture han xin before he revolt.
that why han xin "succeed because of xiao he and die because of xiao he"
