From the Hanyu Pinyin[1] romanization of 哈爾濱/哈尔滨 (Hā'ěrbīn), without syllable-dividing mark (隔音符號/隔音符号 (géyīn fúhào)).
Haerbin
Haerbin can be considered a misspelling of Ha'erbin. In theory, a syllable-dividing mark (隔音符號/隔音符号 (géyīn fúhào)) should be added before a non-initial syllable beginning with a, o, or e. Hence, Haerbin is not allowed since a word made up of ha, er and bin would be spelled as Ha'erbin (cf. Ha'erbin). In practice, syllable-dividing marks are often added or omitted at will.
