I can't. "Shell companies" are also called ready-made companies. It was originally established as a corporate legal form according to the British Company Law. It is a limited company established by the promoters according to the laws of China, Hongkong or England. However, the first director has not been appointed, and no investors have subscribed for shares, so there will be no business, creditor's rights and debts. Shell companies can't build internship certificates. The so-called internship certificate is a proof of the economic income that interns need in their daily production, life and business activities, in bank loans or letters.
