Personally, i don't believe in that particular chinese saying.
It smells more like ego and pride at stake and overriding what
could possibly be a rational decision. If you realized that the
grass is even worse off in the next few kilometers and over the
horizon after crossing over the fence, are you sure you wish to
blindly gallop onwards praying for better pastures?
Or swallow your pride and rejoin the company provided the
policy/situation has changed?
(Not referring to Wanda, of course)
