依托……

依托…… means "relying on; supported by" and is used with the frame 依托 A，B. Use it when you need to express this exact logical relation: develop B with support from a platform, resource, or institution A. Do not use it as a loose translation word; first check whether the two parts of the sentence really match the relation. Common mistakes include dropping 于 in 于-phrases, putting the key word after the object, or confusing similar patterns such as 凭借, 依靠, 基于. In formal writing, keep the clauses complete and avoid mixing two cause-result connectors unless the sentence truly needs both.
