一登龙门，身价十倍yī dēng lóng mén , shēn jià shí bèi

once a fish climbs past the Dragon Gate,its value increases tenfold—having entered the house of a nobleman his fame is ten times greater; rocket into fame after one’s literary (/artistic) work will win the praise of a master

In the Jin dynasty they had to make up to statesmen like Wang Dao and Xie An. This is why the poet Li Bai said:“Once a fish climbs past the Dragon Gate,its value increases tenfold.”
