For his contribution to improving block-printing process for printing Chinese written works, scholars have compared him to the German inventor and blacksmith Johannes Gutenberg.

That year, Liu gathered his troops and prepared to attack Yiwu Circuit (義武, headquartered in modern Baoding, Hebei), which was ruled by its military governor (jiedushi) Wang Chuzhi and allied with Later Liang's archenemy Jin.

Feng took his pen but hesitated to write, and he responded to Li, Your Royal Highness is now planning to conquer the lands south of the Yellow River and then under heavens.

Even if Your Royal Highness disagreed with him, why make this dispute shock all those near and far, such that our enemies would learn this and believe that you and your subjects are discordant?

When Feng's father died shortly afterwards, he left governmental service to observe a period of mourning at Jingcheng.

Later in the year, when Emperor Mingzong and An had more open disputes over the handling of the rebellions by Meng Zhixiang the military governor of Xichuan Circuit (西川, headquartered in modern Chengdu, Sichuan) and Dong Zhang the military governor of Dongchuan Circuit (東川, headquartered in modern Mianyang, Sichuan), An submitted a resignation, which many officials urged him to withdraw.

[1] In 934, Emperor Min's then-chief advisors, Feng Yun and Zhu Hongzhao, did not want Li Congke, who was then the military governor of Fengxiang Circuit (鳳翔, headquartered in modern Baoji, Shaanxi), and Emperor Min's brother-in-law Shi Jingtang the military governor of Hedong Circuit (河東, headquartered in modern Taiyuan) to be entrenched in their posts, and therefore issued a series of transfer orders that, inter alia, transferred Li Congke to Hedong and Shi to Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei).

As Li Congke was ready to enter Luoyang, Feng Dao, in an action that was criticized both at that time and in posterity, requested the official Lu Dao (盧導) to draft a petition for officials to sign, urging Li Congke to take the throne, which Lu refused to draft and rebuked Feng about.

[1] In 935, Li Congke recalled him from Kuangguo to serve as Sikong (司空) — a highly honored post as one of the Three Excellencies — but one that lacked real authority.

The chancellor Lu Wenji thought that the Sikong was supposed to be in charge of cleaning the altar at imperial sacrifices — a ceremonial duty that Feng stated that he would be honored to carry out — but soon Lu figured out that it was inappropriate to ask the highly honored Feng to actually carry out cleanings, and so did not mention that again.

As a sign of further respect, he sent Feng and another senior official, Liu Xu to Khitan to offer those honors, as well as gifts, to the emperor and empress dowager.

[1][14] He was soon given the titles of Situ (司徒, also one of the Three Excellencies) and Shizhong (侍中, head of the examination bureau), and created the Duke of Lu.

However, after Emperor Gaozu soon died, Feng discussed the matter with the imperial guard general Jing Yanguang.

[15] Shi Chonggui gave Feng the honorary title of Taiwei (太尉, also one of the Three Excellencies) and created him the Duke of Yan.

In particular, whereas Emperor Gaozu referred to himself as "son" and "your subject" when writing Emperor Taizong, Shi Chonggui took the position advocated by Jing, that he should only refer to himself as "grandson" and not "your subject" — in other words, leaving the personal relationship intact but at the same time disavowing that Later Jin was a vassal to Khitan.

This displeased Emperor Taizong, who wrote back, rebuking Shi Chonggui for taking the throne without Khitan approval.

[1] In 946, after defeating and then persuading Du Wei (i.e., Du Chongwei, who had removed the "Chong" character from his name to observe naming taboo), whom Shi Chonggui had commissioned as the commander of a major anti-Liao dynasty army, to surrender, the Emperor Taizong of Liao advanced all the way south to the Later Jin capital Kaifeng, forcing Shi Chonggui to surrender.

[17] In 947, Emperor Taizong proclaimed the dynastic name "Great Liao", and summoned the Later Jin military governors to Kaifeng to meet him.

It was believed that these words, along with the intercession of Zhao, was the reason why Emperor Taizong did not carry out mass executions of the Han people.

[18] By spring 947, however, Emperor Taizong was faced with numerous Han mutinies due to his harsh raids against the population.

Meanwhile, Liu Zhiyuan, in this power vacuum, declared himself emperor of a new Later Han dynasty and advanced south, quickly entering Kaifeng after Xiao withdrew from it, and took over most of Later Jin territory.

During the campaign, however, he left the general Yelü Mada in charge of Heng Prefecture (恆州, in modern Shijiazhuang), where Feng, along with other former Later Jin chancellors Li Song and He Ning, had remained.

Yelü Mada was corrupt and harsh, and also put the Han soldiers under severe restrictions, drawing their discontent.

Later in spring 948, Li therefore rebelled at his post as military governor of Huguo and claimed the title of Prince of Qin, in alliance with Wang Jingchong the military governor of Fengxiang and Zhao Siwan, a rebel officer who had seized control of Jinchang Circuit (晉昌, headquartered in modern Xi'an, Shaanxi).

[22] However, the officers under Guo were largely against supporting another member of the Liu family as emperor, as they were fearful of being punished for having sacked the capital.

They subsequently mutinied at Chan Prefecture (澶州, in modern Puyang, Henan) and supported Guo as emperor.

[23] Shortly after the new Later Zhou emperor took the throne, he made Feng Dao Zhongshu Ling, thus restoring him to chancellorship.

[23] Later in the year, the general Murong Yanchao, a half brother of Later Han's Emperor Gaozu, who initially submitted to Later Zhou, rebelled at Taining Circuit (泰寧, headquartered in modern Jining, Shandong).

(After Wang's retirement and subsequent death, Guo Rong was able to stay at the capital and thereafter would remain in the power center.

About a century after the invention of block-printing, Feng Dao significantly improved the printing process, and utilized it as a political tool.
