In the case of Jinzou Yuan, the verdict about Su Shunqin's 'supervisor stealing himself' is tenable in legal theory. It is not appropriate to regard this case as a political persecution of young officials of the new political faction by conservative officials. The relationship between the figures involved in this case can not be simply summarized by conservatives and new deal faction. The impeachment party is not all against the new deal. Song Renzong's attitude towards 'friends' is the key to the retrial of this case. It is the result of political interpretation that the case of Jin Zou yuan becomes an unjust case. Whether it is Su Shunqin's punishment before his death or the later determination of the case of Jin Zou yuan in history books, 'friend party' is a key word that cannot be bypassed.
