低头弯腰不用太高
[dī tóu wān yāo bù yòng tài gāo]
'Bowing low without having to reach too high' can mean humbly approaching others or matters in life but not needing to bow excessively low physically or figuratively (such as sacrificing personal principles). The expression might also imply keeping a modest and approachable attitude in interactions and avoiding unnecessary grandeur or show-off.
