Can Tianjin's 30-year undergraduate program be institutionalized?

I can't. The age limit for applying for a bachelor's degree in Tianjin's teacher recruitment: the age of Chengliu District+Xiqing District (Hongqiao District does not recruit) is under 25 years old, and the age of other districts is under 30 years old. Postgraduate education is divided into master's degree and doctor's degree. The master's degree is basically limited to under 30 years old in all districts of Tianjin (35 years old in Baodi District). In 2023, the age limit will expire at the age of 25 (1997), 30 (1992) and 35 (1987). The specific application deadline depends on the time when the announcement is issued. Generally, the first day after the announcement is the age deadline.
