Spanish to Simplified Chinese: not taller does not necessarily mean shorter
Preserve the relationship rather than just the negative word
Spanish no es más alto que rejects a claim that one person is taller than another. It does not by itself force the conclusion that the first person is shorter: their heights could be equal. A translation that turns this into not as tall can therefore make the claim stronger than the source. The difference becomes important whenever a comparison is being corrected.
Tokyo University of Foreign Studies illustrates this with 他不比我高。我一米七，他也一米七。 The response rejects the suggested height advantage and then states that both people are 1.70 metres tall. The example demonstrates why a negative comparative can be compatible with equality, rather than automatically assert the opposite ranking.
A not-as comparison expresses a different relation
The university lesson separately gives 这座楼没有那座楼高。 for this building not being as tall as that building. It presents 没有 comparisons separately from 不比 and explains that the latter is commonly used to rebut an incorrect comparison. These are not freely interchangeable ways to insert a negative into the same formula.
For Spanish readers, compare a correction saying that one building is not taller with a statement that it does not reach the other building’s height. The first can leave equality possible; the second gives the lower-height reading in this ordinary context. The target should preserve which claim the Spanish writer actually makes, not simply which one sounds like a familiar classroom pattern.
The same lesson’s 今天没有昨天冷。 says that today is not as cold as yesterday. The ordering of the days matters: today has the lower degree of coldness. Switching the comparison terms would reverse the weather information even if all the time words and the adjective survived somewhere in the sentence.
Spanish tan can also introduce a consequence instead of a comparison
The RAE describes tan with an adjective or adverb and como as part of an equality comparison. It separately describes tan followed by que introducing a consequence. A Spanish sentence saying that a place was so cold that something happened is therefore not necessarily comparing its temperature with a second place.
Before choosing the Chinese comparison structure, identify whether the source actually contains two compared terms. A consequence clause supplies a result, not the standard against which the first item is measured. Treating every occurrence of tan as an instruction to build an equality comparison can add an imagined second item or distort the causal relation.
This is especially useful in short evaluations containing a negative. Denying that something is taller, saying it is less tall and saying it was not so tall that a consequence followed are different messages. They cannot be collapsed into a single negative adjective without losing the relationship the source expresses.
The cited Chinese examples retain the simplified characters of the university lesson. They demonstrate a lower-degree comparison and a rebuttal compatible with equality. Read the Spanish comparison as a claim about two values, then preserve whether it asserts a difference, denies superiority or explains a consequence. The visible no alone cannot choose the appropriate target construction.
