Never mock others’ shortcomings.
【Xian'er says so: Don’t laugh at others】
Xiaowu said to Xian’er:
Hey, Er, why are your eyes so small?

Were they not fully opened when you were born? And your ears !

The smog is so heavy here.

I wonder why they have not asked you to blow if away with your giant ears.

And look at your tummy, your little legs, and your eyebrows… You really are something!

I heard you’re in a new cartoon when is it going to be released .Xian’er, the best actor…
Xian’er: Stop talking! I am embarrassed by you.

Xiaowu: Why are you embarrassed by me?

Below are quoted from my Shifu’s new book, Say Good Things—Master Xuecheng’s insight on the path to speaking like a Buddha. 

Those who mock others’ shortcomings are mean-hearted.

They don’t treat others with loving kindness and compassion.
One must be aware that by treating others badly when they are suffering, one is due to have a sad ending.

This is not a curse for personality determines destiny.

永远也不要挖苦和嘲笑别人的短处
贤二如是说：不要嘲笑别人

王小五对贤二说，
喂，二啊，你的眼睛怎么这么小？
是不是一生下来就没睁开？
还有你的耳朵，雾霾这么严重，
有关部门怎么不把你请去招风呢，
真是屈才。还有你的肚子，这小短腿，
还有这眉毛，奇葩啊你。
还有，你主演的动画片什么时候公映啊，
影帝啊你。
贤二说，快别说了，我都替你捏把汗。
王小五说，你凭什么为我捏把汗。

以下来自我师父的《好好说话》
喜欢嘲笑别人短处的人，
根本原因是内心比较刻薄，
不是一个以宽厚慈悲的心面对别人的人。
要知道，当别人有苦难的时候，
如果用一种刻薄的心去对待别人，
自身最终也会拥有刻薄的命运。
这不是诅咒，因为性格决定命运。
