A fact that people born before the early 90s don’t know

(1)While reading a web novel, I suddenly felt the generation gap with the writer
(2)The word “masking wealth” appears, but I thought it was used strangely, so I searched it and found out that the word “masking wealth” in the textbook changed after the 7th curriculum. LOL I found out for the first time today since I was born

(1)I found out that the indulgence was changed to the indulgence It’s a modified word from a textbook
(2)When I solved the meaning, it seems that it is more clearly classified as meaning that the sin remains, not the sin, but the punishment for the sin does not disappear even if it is not punishedIt’s as shocking as when I found out that Odd had switched to iodine
