   🕒 01:13
3. Add 1/3 tsp salt to the thinly sliced cucumber, rub for 30 seconds, and let it sit for 10 minutes.
   🕒 01:25
4. Rinse the salted cucumber, squeeze out the water firmly, and then pat dry with paper towels.
   🕒 01:39
5. Grate 1/8 onion. 【This is the trick!】 Grating the onion tightens the flavor of the potato salad, making it taste like it's from a restaurant.
   🕒 02:04
6. Mix the grated onion with 1 tsp sugar, 1 tsp vinegar, and a pinch of salt.
   🕒 02:27
7. Boil enough water in a pot to cover 1 egg.
   🕒 02:53
8. Add salt (amount not specified) and the egg to the boiling water, and boil for 12 minutes to hard-boil.
   🕒 03:02
9. Turn off the heat for the boiled egg, drain the hot water, and cool in cold water for 10 minutes.
   🕒 03:14
10. Peel the cooled hard-boiled egg and finely chop it.
    🕒 03:22
11. Peel 300g of potatoes, remove any eyes, and cut into 1.5-2cm pieces.
    🕒 04:02
12. Soak the cut potatoes in water for 10 minutes to remove bitterness.
    🕒 04:50
13. Drain the potatoes and place them in a pot. Add enough water to cover the potatoes.
    🕒 05:08

15. Once boiling, reduce to medium heat and simmer for 8 minutes.
    🕒 05:48
