Although a matter may be considered trivial,
事虽小,
but if it is wrong to do it or unfair to the other person, do not do it thinking it will bear little or no consequence.
勿擅为。
If you do, you are not being a dutiful child because parents do not want to see their child doing things that are irrational or illegal.
苟擅为,子道亏。
Even though an object may be small, do not hoard it.
物虽小,勿私藏,
If you do, your parents will be heartbroken.
苟私藏,亲心伤。
Whatever pleases your parents is fair and reasonable; try your best to get it for them.
亲所好,力为具,
Whatever displeases your parents, if within reason, cautiously keep it away from them.
亲所恶,谨为去。
When your body is hurt, your parents will be worried.
身有伤,贻亲忧,
If your virtues are compromised, your parents will feel ashamed.
德有伤,贻亲羞。
When you have loving parents, it is not difficult to be a dutiful child.
亲爱我,孝何难,
If your parents hate and you are still dutiful to them,
亲憎我,
only then will it meet the standards of the saints and sages for being a dutiful child.
孝方贤。
