Am I reading [the same version](http://www.wcai.net/poetry/gelu/gelu00.htm) as yours?  So what do you think about the tone 平仄 of the 1st verse of my sample poem?  You describe Prof. Wang's work as "systematic", so you might be able to find a "systematic" way to tackle this problem.  It seems that from chap 2 sect 3 & 7 that the tone of my sample poem is not regular enough.  I'd love to hear your feedback.

If you want an example from the masters: 曲江其二 (The Qu River, No. 2) by 杜甫 Du Fu has a deflected 仄 in the 5th character of line 6 out of 8. [Although caveats about emulating the way the masters of an art break the rules apply!]

@Michaelyus Thanks for comments.  I've checked that poem.  The tone of 6th line is regular "仄仄平平仄仄平".  The tone of the upcoming line "中仄平平仄平仄" is a well-known form of aogu 拗句 known as 出句自救.  What I'm not sure is issue of isolated flat tone on second last character of a verse.

Tone 平仄 of the 5th character in a seven-character jueju 七絕
# Tone 平仄 of the 5th character in a seven-character jueju 七絕

(Asked by: username_0 on 2019-03-21)

In writing regulated verses 近體詩, there's a saying "一三五不論，二四六分明。" (We don't care the tone 平仄 of the odd-numbered characters in each line, but we care about that of the even-numbered ones.)

However, [Baidu's page about seven-character jueju 七絕](https://baike.baidu.com/item/%E4%B8%83%E8%A8%80%E7%BB%9D%E5%8F%A5?timestamp=1553202231268) shows that the tone of the 5th character of each line is fixed.

I wonder if one has the freedom to choose the tone of the 5th character in a seven-character jueju.

Let's take a concrete example. Is it ok to take a deflected 仄 tone at the 5th character at the first (out of four) verse?

Short answer to my main question: yes, as long as it's not causing problems like "three consecutive flat-toned end" (三平尾), "three consecutive deflated-toned end" (三仄尾), "isolated flat-toned verse" (孤平), etc.

I think I've found the answer to my question by chance, as a side-product of today's work, which involves "塞雲" (clouds along the territory's boundary). I tried searching on Souyun (搜韻), and I found this poem by luck.

> 書事五首（壬午） 其四 晚清 · 雷鐘德
>
> 水陸軍聲羽檄紛，詔書特起故將軍。  
> 但聞巴蜀索軍實，不見旌旗卷塞雲。  
> 胡騎數傳邊報急，秦庭可有哭聲聞。  
> 聖恩寬大惟行賞，敕賜金錢策戰勳。

In the 3rd verse, "索軍實" has two deflated-toned word surrounding one flat-toned word. I've checked the [tones of this poem on Souyun](https://sou-yun.cn/Query.aspx?type=poem1&id=273511) so I'm 100% sure about this.

"一三五不論，二四六分明。" is just a rule of thumb to help people quickly get the main idea. It's not always accurate or reliable. The 5th character is often very important in terms of 平仄.

As the other answer suggests, Wang Li's book 诗词格律 is highly recommended. In my understanding, the tone of the 5th character in your first verse is not good. The sentence should be 平平仄仄平平仄.

It is actually a big topic on the tone of Chinese poetry, even in different dynasties the rule is slightly different. I recommand you read Wang Li's (王力) book named 《诗词格律》, which has a systematic description on it.
