+commits of unit test in the repository 
+before you implement the function. 
+
+**Hint:** you are challenged to work iteratively and efficiently. 
+Do one thing at a time. Commit and push regularly. 
+It is not possible to complete all your ideas in a very limited time. 
+Make sure you can choose the minimum requirements such as identifying
+a pet that has the biggest number of pet descendants, but stay aware
+of the owner vision of having a unique feature/information of the clinic.

+
+What do you have in mind for such a promising and profitable opportunity?
+As an advanced programmer, you have learned the issue about scalability, 
+micro-services, design pattern and other advanced topics related to software 
+scalability and maintenance.
+
+Given a very limited time that you still have, try to:
+- Write in your ``readme.md``, what is your plan related to advanced programming. (make it brief.)
+- Create a new branch. The branch name is ``bonus``
+- Work on your plan, the best you can in that branch. 
+- Make sure you **commit** and **push** before the deadline (**12:30 today!**). 
+- If your plan is not involving coding, try to give
