Among the ten pairs of brothers in Liangshan, six pairs of brothers originally lived together, and their social status was no different, and the main deeds were basically similar. Logically, their ranking after Liangshan should also be relatively close. But judging from the situation of Liangshan Dajuyi later, there are five pairs of brothers who are like this, but one pair of brothers is very special. The older brother ranked twenty-fourth in Tiangang, while the younger brother belonged to the Earth Fire and ranked eighth. They just didn't cover Mu Hong and xiao covered mu chun brothers. So, what makes these two brothers different? To answer this question, we must first start with the life of the M Moser brothers.

Mu Hong and Mu Chun jr. both live in Jieyang Town and are rich local households. Because of their wealth and power, the brothers ran amok in the local area and committed misdeeds, and were known as one of the "Three Hegemons of Jieyang".
Song Jiang stabbed Cangzhou through Jieyang Town, saw the jianghu artist, the sick insect Xue Yong selling art on the street, saw Xue Yong's martial arts are good, on a whim, he rewarded Xue Yong with five or two pieces of silver, who knew that this move almost brought himself the disaster of killing. It turned out that the Mu brothers had a rule, and anyone from outside jieyang town to make a living must first go to Mujiazhuang to pay tribute.
Xue Yong did not know this rule and came to the street to sell art, which naturally annoyed the Mu brothers. The brothers ordered the townspeople not to give Xue Yong a reward. Song Jiang naturally did not know that Jieyang Town had this rule, a shot was five or two pieces of silver, which made Mu Chun very dissatisfied, and he wanted to teach Song Jiang a lesson, but he was knocked to the ground by Xue Yong and taught a lesson.
Mu Chun was beaten, how could he give up. That night, Mu Chun and his brother Mu Hong captured Xue Yong and beat him violently, and then took the dealer everywhere to arrest Song Jiang. Song Jiang was cornered, and in a panic, he boarded Zhang Heng's thief ship and was almost killed by Zhang Heng. Fortunately, Li Jun, the mixed river dragon, appeared in time and revealed Song Jiang's identity, which eliminated a misunderstanding. After that, Song Jiang returned to Mujiazhuang and was warmly welcomed by the Mu brothers.
After Song Jiang was in distress in Jiangzhou, Chao Gai took the Liangshan brothers to rob the court and rescue Song Jiang. After that, the crowd came to the White Dragon Temple. Soon after, the Mu brothers, together with Li Jun and others, also came to the White Dragon Temple to meet Song Jiang, and then they burned the Wuwei Army together and eliminated the culprit, Huang Wenbing. Later, the Mu brothers burned down Mu Jiazhuang and took their father Mu Taigong and all the members of the family to Liangshan.
In the subsequent confrontation between Liangshan and local armed forces and officials, the Mu brothers did not have much opportunity to perform, the only time was that Mu Hong had a head-to-head with Zhu Hu during the "Three Dozen Zhujiazhuang", and the result was a draw. His younger brother Mu Chun had no record of fighting in all the battles. However, since the two brothers went up the mountain, Song Jiang had paid special attention to them.
After the end of the "Three Dozen Zhujiazhuang", his brother Mu Hong, under song Jiang's arrangement, guarded the third pass of the cottage with Liu Tang. The younger brother Mu Chun was in a more special position, responsible for the money and grain of Liangshan, and later responsible for the construction of the cottage's houses and fences. At the time of liangshan's great gathering, his elder brother Mu Honggao ranked twenty-fourth in Liangshan, and was one of the eight tiger riders of the Ma Army, alongside Hua Rong, Xu Ning, Yang Zhi and others who were highly skilled in martial arts. Although his younger brother Mu Chun ranked only eightieth, he was also one of the infantry generals, alongside infantry generals such as Fan Rui, Li Gong, and Xiang Chong.
As mentioned earlier, after going up the mountain, neither Mu Hong nor Mu Chun performed much. After Liangshan was recruited, the two brothers had almost no outstanding performance, which showed that if it was ranked according to ability, Mu Hong could not rank at twenty-four, let alone become one of the eight tiger riders of the horse army. So, why did Song Jiang care so much for the Mu brothers?
There are two main reasons for this. First of all, the Mu brothers were brought to Liangshan by Song Jiang himself, and belonged to Song Jiang's concubine lineage, and Song Jiang would naturally take special care of them. Among these two brothers, Song Jiang chose his brother Mu Hong as the key care object, not only to rank him as Tiangang, but also to specially arrange for him to enter the Eight Tigers of the Horse Army.
Second, despite their mediocre abilities, the Medes were well-off. When they first went to Liangshan, the Mu brothers gave all the family assets to Liangshan. This made a significant contribution to the early development and growth of Liangshan. Based on these two reasons, as the representative of the Mu family, Mu Hong's ranking and status will be so high in Liangshan. However, judging from the actual performance of these two brothers, they were both mediocre people, and they had never even killed any enemy generals, and they were the most unworthy of the ten pairs of brothers in Liangshan.
