Do I need to open a lease for the renewal of office space?

No need. According to the "Bidding Law of People's Republic of China (PRC)", if the company has reached an agreement with the property owner to renew the lease of office space, there is no need to rent it again or invite public bidding. Government departments, institutions and other public institutions need to choose the housing lease through bidding or public bidding to ensure fairness, justice and transparency.
