Born in a middle school teacher's family in Shashi, Wang Guohua. Father Uradislav Skolodowska is a middle school math teacher, and mother Brogny Slova Boguska Skolodowska is the principal of a boarding school for girls. The baby's name is Mabya Sklodowska. Maria, who traveled for the fifth time, has three sisters and one brother, namely Sophie, Broger Shirava, Helena and her brother Joseph.

At that time, Poland was ruled by Russian czar Alexander II (1818-1881).

1868 One year old

His father Scolo Dovski is the assistant principal of Novolipki public middle school. My mother was weak and suffered from lung disease, so she had to resign as the headmaster of a girls' school.

The whole family moved out of the house on Frida Road where they had lived for eight years.

1873 Six years old

Father was demoted and his salary was reduced by the Russian authorities. In order to subsidize their families, boarding students are admitted to study at home. There were only two or three people at first, and then it increased to ten people.

Maria went to a private boarding school, and the principal was Ms. Lucy Kolska.

1879 ——1878 Nine and eleven years old.

Elder sister (1876) suffered from typhus, and mother (1878) died of lung disease for a long time.
