Normalization about own data

[BENHSU0723]

hello, i'm try to train on my Chinese datasets. During the data processing , i have some confusion below.

1. Should i Normalize the data into same size to get better result??
2. The textflow in datasets combined with vertical and horizontal , should i Rotate them into same direction ?

by the way, i would choose TRBA (TPS-ResNet-BiLSTM-Attn) for train.

i don't have too much base knowledge about deep learning, thank for reply !!
