I was advocating for HQ for Silk Road in Chinese capital which could function just the way Trade Company wonder works for Europeans, because Silk Road's HQ can have the very same meaning and effect Trade Road HQ has for Europeans: brunches give gold to HQ. In that context, not having many Chinese cities with Silk Road branches makes sense: entire China collects goods to capital which sells it to the closest city west of it. Traders from there sell things to the neighbouring city further west and so on. Thus you get Silk Road cities benefiting from Silk Road branches while Chinese capital benefits from Silk Road HQ, and no need for other Core Chinese cities to have any branches...
