Personally, Shengjuntang, Yaowangyuan and Flavor Gate don't make money. Hidden unsealing symbols are much cheaper than weapons.

It is recommended to match three sets with three sets:

Tiejiangfang+Shifang+Metallurgy Village+Wanjintang

Taishangmen+Ceramic Workshop+Fengnianhui+Mufang

Taishangmen+Bailiezhuang+Flavor Door+Wooden Workshop (this figure is auxiliary, mainly animal bones, and wolf bones are very expensive).
