Physical education teacher Wang Yongyong asked many of his friends and learned quite a bit about knee surgery. He also learned some about Zhang Fan as well. Although Zhang Fan was still a young doctor, he was quite famous in Chasu City Hospital. Wang Yongyong also made a trip to go visit Guli. Wang Yongyong was a former professional athlete, and could tell that Guli didn't seem to suffer any negative side effects from her previous major knee injury. Her knee joint was quite flexible and sturdy even after the surgery.
