On the 4th of April, PKUAA@Edinburgh organised a celebration event for Dr. Wang Du and Dr. Xie Jinhan who had successfully passed their viva. Many congratulations to them! They very kindly shared their experience of viva with the rest alumni, all Doctor-To-Bes. This event was also a farewell party for those two, as they soon will be leaving UK. We wish them all the best for their future and look forward to next gathering wherever it might be!
