This varies among the institutions. Many will provide reimbursement for a round-trip international economy air ticket at the completion of one academic year. Others will provide reimbursement for one-half of the international air ticket at the end of one academic year.
Some institutions provide one-half of the international air ticket at the completion of one contracted semester. Normally, the terms are written into the contract. Reimbursement is in Chinese Yuan (RMB) and is not considered as part of the salary for conversion purposes.
