The teaching assistant Felix Xu Ziling could not be contacted for the past two days, and the SHD platform could not be accessed! I tried to contact Wang Shouren, Zhou Junyan, Li Zian, teaching assistants, Miss Lin Baoyi and others through Line, but I couldn't find them all! I can't find any way to withdraw the money! Please return the money as soon as possible! Those are all my hard-earned and hard-earned money ah!
