Anger Not in Chinese / Japanese...

不能咬人就别龇牙 is a Chinese proverb that literally translates as: [if you] can't bite people, don't bare [your] teeth.

Figuratively, this means: Don't show your anger if you can't do anything about the situation.

Some will also say this means “Don't start a fight that you cannot win.” Others will say it means that you must be willing to back up your words (perhaps with your fists).

十戒 means Ten Commandments or Ten Precepts.

In the Buddhist context, these are prohibitions consisting of five commandments for the layman:
1. Not to destroy life 不殺生 Pāṇātipātāveramaṇi.
2. Not to steal 不倫盜 Adinnādānāver.
3. Not to commit adultery 不婬慾 Abrahmacaryaver.
4. Not to lie 不妄語 Musāvādāver.
5. Not to take intoxicating liquor 不飮酒 Suramereyya-Majjapamādaṭṭhānāver.

The ten commandments for the monk are the preceding five plus:
6. Not to eat food outside of regulated hours 不非時食 Vikāla-Bhojanāver.
7. Not to use garlands or perfumes 不著華鬘好香塗身 Mālā- Gandha-Vilepana-Dhāraṇa-Maṇḍana-Vibhūṣanaṭṭhānā.
8. Not to sleep on high or broad beds (chastity) 不坐高廣大牀 Uccāsayanā-Mahāsayanā.
9. Not to take part in singing, dancing, musical or theatrical performances 不歌舞倡伎不往觀聽 Nacca-Gīta-Vādita-Visūkadassanāver.
10. To refrain from acquiring uncoined or coined gold, or silver, or jewels 不得捉錢金銀寶物 Jātarūpa-Rajata-Paṭīggahaṇāver.

These original Buddhist commandments date back to about 2500 years ago. The English definitions above are followed by Chinese characters and original Pali pronunciation.

Under the Māhayāna Buddhism, these ten commands for the monk were changed, to accord with the new environment of the monk, to the following: not to kill, not to steal, to avoid all unchastity, not to lie, not to slander, not to insult, not to chatter, not to covet, not to give way to anger, to harbor no skepticism.

In Japanese, 無心 means innocent or without knowledge of good and evil. It literally means “without mind.”

無心 is one of the five spirits of the warrior (budo) and is often used as a Japanese martial arts tenet. Under that context, places such as the Budo Dojo define it this way: “No mind, a mind without ego. A mind like a mirror which reflects and dos not judge.” The original term was “mushin no shin,” meaning “mind of no mind.” It is a state of mind without fear, anger, or anxiety. Mushin is often described by the phrase “Mizu no Kokoro,” which means “mind like water.” The phrase is a metaphor describing the pond that clearly reflects its surroundings when calm but whose images are obscured once a pebble is dropped into its waters.

This has a good meaning in conjunction with Chan / Zen Buddhism in Japan. However, out of that context, it means mindlessness or absent-mindedness. To non-Buddhists in China, this is associated with doing something without thinking.
In Korean, this usually means indifference.
