I think as a way to solve the problem of the child origin while keeping him rightfully is by saying that the child is born from her sister and she can babysit the child as his aunt till he grow up and know the truth and by that the child will be rightfully Tang's son from known origin

I enjoyed the book although it has loose ends and i don't understand how the MC have avoided all those powerful people and companies in real life and for me I guessed with all those girls around the MC we will see some romance but it didn't happen but the book has it charm to make the reader continue till the end
