The character for “seven” is represented in stories by a diary (a weekly planner where you look seven days ahead to see appointments, rather than a personal journal).
When writing this character, notice that the sloping stroke extends well to both sides of the hook stroke, in contrast to 匕 which we’ll meet later (206a).

[七十五 (4, 36) qīshíwǔ seventy five]

/ You look in your diary, and notice that in seven days’ time your car is due for new wheel s. The giant has offered to get them for you cheap.
