Okay, if you look at ZWY's schedule, it has a smiley face on the 3rd day, when the wedding robbery takes place? LOL!

Zhang Wanyi's schedule
Eps1-3 (poinciana flower, crown - becoming king, seeing Xiao Yao at the poinciana forest in Shen Nong mountain)
Eps 4-5 (wine bottle and heart - getting drunk with Xiao Yao before she leaves for Haoling to prepare for her wedding)
Eps 6-7 (smiley face - pleased that the wedding didn't happen)
Eps 8-9 (pouch - the pouch Xiao Yao embroidered for him which contained pills to ward off poisons)

And here's Yang Zi's schedule. It has what looks like a wine jug, lotus?, snow and frozen tree, and flowers.

Yang Zi's schedule
Eps1-3 (wine jar - getting drunk with Cang Xuan to celebrate his ascension to the throne)
Eps 4-5 (white flowers/lotus? - can't think what this is supposed to represent. The white lotus is symbolic of Xiang Liu, but I don't recall it being specifically tied to him in the drama/script. If it is Xiang Liu, is this supposed to refer to the appeal to him via the crystal globe?)
Eps 6-7 (snow and snow-covered trees - the one month at Qingshui Town after being taken away from the wedding)
Eps 8-9 (pink lotus - the flower Jing jumped into the lake to pluck for her during the Hou seduction period)
AH :
But if XL/FFB taking XY away from the wedding occurs in episode 6-7, then the flower for episodes 1-3 can't represent the wedding.
I believe it is the Ruomu flower which Cang Xuan gave her just before he went to the prayer ceremony when he did not know if he would come out of it unscathed. When they celebrated his acscension to the throne, she returned the Ruomu flower back to him, saying she could not keep what is meant to be given to the woman he loved the most.
