Similar topological phases may also arise from in-plane ferromagnetism through the breaking of certain mirror symmetries in kagome materials. In this work, we show that the interplay between magnetism and mirror symmetries makes ferromagnetic kagome systems a versatile platform for realizing nontrivial topological phases, with the orientation of magnetic moments\n                    <jats:inline-formula>\n                      <jats:tex-math>\n                        \n                      <\/jats:tex-math>\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" overflow=\"scroll\">\n                        <mml:mrow>\n                          <mml:mrow>\n                            <mml:mover>\n                              <mml:mi>m<\/mml:mi>\n                              <mml:mo stretchy=\"true\">^<\/mml:mo>\n                            <\/mml:mover>\n                          <\/mml:mrow>\n                          <mml:mo stretchy=\"false\">(<\/mml:mo>\n                          <mml:mi>\u03b8<\/mml:mi>\n                          <mml:mo>,<\/mml:mo>\n                          <mml:mi>\u03d5<\/mml:mi>\n                          <mml:mo stretchy=\"false\">)<\/mml:mo>\n                        <\/mml:mrow>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    at lattice sites serving as a key tuning parameter.
