The Yin family started off as a day-to-day family and was considered an old manufacturing company. In Yin Huai's generation, he had an older brother who was almost ten years older than him that had already entered the company and made it to the top.
With a capable eldest son to support the family, the Yin couple did not have any strict requirements for Yin Huai. It was fine as long as he did not cause big trouble for the family outside.
If it was said they doted on him, they did dote on their youngest son. But if they said they didn't feel disappointed, they simply didn't have any expectations for him. After knowing this, Yin Huai was too lazy to work hard and just muddled along.
"Don't you have anything you want to do? Are you going to just sit around and do nothing for the rest of your life?" Le Wan told him to go back and think about it.
