          Criteria
        • REALITY

          1. The current word referring to reality is shí 實 (ant. xū 虛 "pretended reality"), but the word acquired this meaning rather late (meaning "object" in earlier texts).

          2. Qíng 情 (ant. wěi 偽 "fake") and chéng 誠 (ant. zhà 詐 "fraudulent") are often used interchangeably to refer to the real facts versus what is pretended or what is merely superficial.

          3. Zhēn 真 (ant. jiǎ 假 "faked") refers to the genuine inner state of something, the ultimate truth about it.

        • EMPTY

          1. The most geneal word is xū 虛 (ant. shí 實 "substantial and full") which can refer both to physical emptiness of a space and to abstract emptiness or tenuousness as a philosophical concept.

          2. Kōng 空 (ant. mǎn 滿 "filled up") generally refers to literal emptiness of a container, but used adjectivally the word also has abstract uses as in kōng yán 空言 "empty words, abstract insubstantial discourse".

          3. Wú 無 (ant. yǒu 有 "existence") refers to the philosophical abstract construct of "nothingness, emptiness".

          4. Kuò 廓 and kuàng 曠 emphasise the expansiveness of the empty space.

        • FILL

          1. The most general and current word in this group is probably yíng 盈 (ant. xū 虛 "empty out") which refers to any filling up or filling in, abstract or concrete.

          2. Chōng 充 refers to the concrete filling out completely of a container or a suitable empty space with (often desirable) physical substances.

          3. Sài 塞 emphasises the nuance of filling in a space not necessarily designed to be filled in so as to block the free passage of other substances.

          4. Mǎn 滿 is a word that was rather late to gain currency, replacing certain usages of yíng 盈, and it refers to the filling out of all of an empty space, with large amounts or large numbers of some specified kind of objects.

          5. Tián 填 is originally to fill out something so as to make a level surface.

        • RUINS

          1. The current standard word for ruins is xū 墟 / 虛.

          2. Qiū 丘 "mound" is sometimes used periphrastically to refer to ruins.

        • ILLUSION

          This concept was elaborated in Buddhism, but transferred uses of words like xū 虛 "empty, illusory" do perhaps convey the meaning in pre-Buddhist Chinese.

        • ABSTRACT

          [COMMENDATORY/DEROGATORY]

          [EXPLICIT/IMPLICIT]

          1. Xū 虛 derives its sense from the meaning "physically insubstantial" and refers negatively to something having only tenuous links with concrete things.

          [EXPLICIT]

          2. Wēi 微 derives its sense from the meaning "slight; tenuous" refers to something being so subtle and only indirectly suggestive as to have no direct manifest reference to any concrete reality or meaning.

          [IMPLICIT]

          3. Kōng 空 derives from the meaning "physically empty (space)" and refers to something being empty in a transferred sense so as to have no manifest reference to concrete reality.

          [DEROGATORY], [EXPLICIT]

        • FAKE

          1. The current general word for faking something is jiǎo 矯 and the typical focus is on fraudulence involved.

          2. Wěi 偽 (ant. zhēn 真 ) focusses on the artificiality rather than natural or proper provenance of the product.

          3. Xū 虛 (ant. shí 實 ) focusses on the insubstantiality of the product, and the word is normally used adnominally.

          NB: Jiǎ 假 (ant. zhēn 真 ) focusses on something standing in for something else that is the genuine thing, but this usage was late to develop (HOUHANSHU).

        • TRUE

          1. The most current word is rán 然 "it is so" (ant. fǒu 否 "be untrue"), and what is said to be so is a yán 言 "statement', and things are claimed to be as stated in that statement.

          2. Kě 可 refers to logical or ethical acceptability.

          3. Xìn 信 (ant. zhà 詐 "fraudulent and not reliable") refers prototypically to reliablity as information.

          4. Shì 是 (ant. fēi 非 "wrong") refers prototypically to what invites assent or approval.

          5. Zhēn 真 (ant. jiǎ 假 "fake") typically refers to what contains nothing faked or unreal and is genuinely true.

          6. Dāng 當 (ant. guò 過 "wrong") refers prototypically to what fits the facts and does not deviate.

          7. Yǒu 有 (ant. wú 無 "there is no such fact")refers abstractly to the occurrence of an event or the truth of an abstract proposition.

          8. Chéng 誠 (ant. wěi 偽 "faked") refers to honest truth. (Note that chéng 誠 normally means "earnest" in early texts and has nothing to do with this meaning.)

          9. Shí 實 "real and true" (ant. xū 虛 "only apparently") refers to something not being a figment of the imagination. See REAL.

        • UNTRUE

          1. Fēi 非 refers to something being untrue and thus to be rejected.

          2. Xū 虛 claims that something is to be rejected because it is insufficiently founded on solid fact.
