Why didn't China Post successfully prosecute?

If China Post successfully sued but failed to implement it, there may be many reasons:

1. Difficult to execute: it may take some time and resources to execute the judgment. If it is difficult, it may not be implemented in time.

2. High execution cost: It may cost some money to execute the judgment. If the implementation cost is too high, it may not be able to bear these costs, resulting in failure to implement.

3. The person subjected to execution does not have sufficient property: if the person subjected to execution does not have sufficient property to execute, the judgment may not be executed.

4. Complicated execution procedures: The execution of the judgment may need to go through certain procedures. If the program is too complicated, it may not be executed in time.

In a word, the reason why China Post successfully sued but failed to implement it may be the result of a combination of various factors, which need to be analyzed in detail and corresponding measures taken to solve the problem.
