I would say its really interesting to watch because the usual drama aired on TV are mostly focused on romance which also quite common. Not forget to mention most drama has a quite similar storyline flow, where we can predict the ending of the story but Joy of Life/Qing Yu Nian is different. Though the story look simple but its actually complicated too as there's a lot of mystery upon another one. A worth series to me and i also love the storyflow. It is compact for a series drama, it didn't dragging the story like other drama does.
Overall with the story line, actor, actress, and also the production crew did so well with the drama and i totally looking forward for the second season!
