According to experts, "Fu" and "Fu" are different ways to write the same surname. "Fu" is the white word for "Fu". This is due to the historical turmoil and the reform (simplification) of writing. Because the reform of Chinese writing system is not mature in some aspects after the founding of the People's Republic of China, the writing of "symbol" has appeared in household registration management and various files. With the passage of time, people gradually accepted the substitution of "Fu" for "Fu". In fact, in the expression of surnames, this is completely wrong.
