Ju Si-gyeong was born as the second son in Bongsan, Hwanghae-do in 1876, and was adopted as the adopted son of his second eldest father, Ju Hak-man (Joo Joo-jin), when he was 12 years old. The site of the 'Yongbieocheonga' building in Naesu-dong, Jongno-gu, Seoul is the site of Ju Si-gyeong's house. It is the site of a house where he lived until he was thirty-nine and then died. (It is said that after the teacher passed away, his wife sold it because of family difficulties.) Ju Si-gyeong was born on November 7, 1876, in Chadolgae, Insan-myeon, Pyeongsan-gun, Hwanghae-do, as the second son of six siblings between his father, Joo Ju-seok, and his mother, Jeonju Lee. He later moved to Mureunggol, Ssangsan-myeon, Bongsan-gun, Hwanghae-do, and moved to Seoul in 1887, when he was 12 years old, as the adopted son of his second eldest father, Ju Hak-man, who was living in Seoul and doing business. At that time, his uncle's house was “31 Tong 4 Ban, Chang-dong, Seobu Yangsaengbang, Gyeongseong, Joseon (currently Namdaemun-ro side)”. He lived here and moved to Naesu-dong. (I don't know the exact time of moving)
