University professors can make money by doing projects. There are two kinds of projects. The vertical project is the national research fund, and the horizontal project is the enterprise. The horizontal topic is that the school charges a certain percentage of fees, and then the rest goes to the tutor. Therefore, university teachers can get paid to do horizontal work.

Vertical projects refer to "projects" that get funds directly from the scientific research funds included in the financial plan of the state, ministries, provinces and cities, including 973 and 863, natural science funds, social science funds, military projects, science and technology planning projects and projects of various ministries and commissions. Horizontal projects are projects that obtain R&D funds through technical cooperation. Horizontal projects are generally projects formulated by specific departments and enterprises to solve difficult problems and technical difficulties in their work, and direct cooperation between the project entrusting party and the entrusted party can be realized by providing project funds and R&D rewards. Most horizontal projects are entrusted by local governments to some institutions and enterprises, to specialized institutions or R&D units to tackle key scientific and technological problems or to be implemented as projects.
