Abstract：
The Standard Model (SM) is a highly successful effective theory. However, even within the model, a few long-standing questions still neededto be answered. One of the prominent unsolved puzzles of the SM is: ``Why the masses of SM fermions are so different?'',  also known as the flavor puzzle. In this talk, I will briefly review the flavor problem and discuss a new gauged horizontal U(1) model we constructed to explain the observed pattern of SM charged fermion masses.
