The chinese favor system is quite standardized with very little room for expression of the system. Most every game will average around 30 favor/min one of the lowest peaks of any civilization. With kuafu and techs it is almost always suboptimal to purchase an actual myth unit until late mythic and then given the high costs of chinese myth units you can purchase about one per minute.
The reason seems to be that they are the only civilization without any technology for increasing favor generation. I understand early techs could have a large impact on kuafu production but a friend had a very good idea for a mythic tech with Zhurong. If you changed his farm tech to provide trickles of favor per farm it would provide an actual tech path for China to produce myth units. It would still be late game but could give them an option to compete with Egyptians and Atlanteans in favor production.
What do you think? I think they did a great job on the myth units and it is a shame you almost never get to make them.
