I kinda lost and confuse here, did i miss something to find and get neither Zhu Tu and Zhu Beng?. I can't find them in family tree, character finder, and spy network. Im so frustrated i even already fight against Zhang Jiang faction by using Yuan Shao, Zhang Yan, Dong Zhou, Gongsun Zan, Ma Teng, Liu Chong, Yuan Shu to trigger the event of Zhu Tu and Zhu Beng to join my faction, but nothing happened.

I try campaign at AD 190 - 200 and AD 194 - 203 (world betrayed), but still nothing i even try to destroy completely her faction but the event still won't show up. Please help me it's been 8 month i try again and again to find them because it's only those two who never show up.
If this is some kinda bug or something please developer fix this i don't care about MOH campaign right now, for now please fix this one just please i beg you i want to try them so bad. The reason i begging to you it's because you not put those two in custom battle too.

And for Lady Trieu it's make me feel like boring (like waiting Zhunge Liang and Pang Tong event) event to wait for her event to show up (at AD 207 if i remember) and after the event show up it's *puff* nothing happend and the game continue without Lady Trieu around. I can' find her anywhere too (same as Zhu Tu and Zhu Beng problems), How can i get her? i still don't understand.
