Ox and Tiger
Lots of tension and lots of hardwork to make the relationship work.
Ox is slow and hardworking while the tiger is fun and and flighty. Ox is sees this behaviour as unacceptable. However with the determination of the ox and the courage of the tiger, this match is good.
For success, both parties have to give each other freedom and space. It takes a lot of effort and patience for this relationship to work but it can.
