"Leave without promotion" is a common name. If you fail to complete the contract in the first employment period, you will not be renewed in the next employment period. There will also be an agreement on scientific research output in the contract, but the core indicator is the promotion of professional titles, including the promotion of lecturers to associate professors, and the conversion of some young talents to professors after the expiration of the plan. This kind of contract system and life tenure system is the "universal" policy of the domestic university teacher system in recent years.

"Promotion or resignation" is an assessment system, not a punishment system. Career establishment is no longer an iron rice bowl, and "not renewing the contract" is not "terminating the career establishment". Dismissal is a punishment, but non-renewal is a normal personnel management behavior.
