description	The invention belongs to the technical field of gas turbine guide blades, and particularly relates to a turbine guide blade and a cold air flow guide part of a front cold air cavity of the turbine guide blade. A basin side air film hole, a front air film hole and a back side air film hole are respectively formed in the cavity wall of the front cold air cavity of the blade body; air inlets are formed in the inner end and the outer end of the blade body; the cold air flow guide part is arranged in the front cold air cavity and divides the front cold air cavity into a front edge cooling cavity, a blade back cooling cavity and a blade basin cooling cavity; the front edge cooling cavity is communicated with one air inlet, and the blade back cooling cavity and the blade basin cooling cavity are communicated with the other air inlet; and different cooling cavities are correspondingly communicated with different air film holes. According to the scheme, the cold air fed into the front edge, the blade basin and the bla
