Lin Yu really thought too little of Lin Qiang.
Lin Qiang knew he was in trouble, and since entering, he had ratted out the thugs but had not mentioned a word about Lin Yu's involvement.
What he told the police was that he had seen Lin Aiguo beating Lin Yu because of Lin Xia and the others, and out of anger, he wanted revenge on Lin Xia and the rest, claiming that breaking into the convenience store was a spur-of-the-moment decision.
He felt lucky that he had gone to drink with the thugs but did not say it was Lin Yu who had told him to do it, only that he wanted to vent for Lin Yu.
Otherwise, Lin Yu might have gotten involved as well.
He thought it through very clearly; his mother only had two children—she couldn't afford to have both locked up, as that would dishonor her, and she would go insane.
Lin Qiang and the thugs were sentenced to ten years, which was considered light compared to others.
This was not without the results of Lin Yu seeking help from Chen Gang.
