东A西B
dōng A xī B
The structure 'East A West B' (东A西B)
Explanation
东A西B (dōng A xī B) is a fixed four-character construction (a template-based idiom) that inserts 东 (dōng 'east') and 西 (xī 'west') into two verbs A and B to describe an action done all over the place, in every direction, without order, or the toil of dashing around many places.
东 (dōng) + verb A + 西 (xī) + verb B, where A and B are usually two verbs close in meaning or complementary to each other (such as 挑 tiāo 'pick' / 选 xuǎn 'choose'; 奔 bēn 'rush' / 跑 pǎo 'run').
when you want to vividly depict doing things haphazardly, all over the place, or bustling around everywhere; it carries a figurative flavor and can be used in both speech and writing.
this is a fixed template; here 东 and 西 no longer carry the real directional sense of 'east, west' but merely indicate 'here and there, everywhere'.
not every pair of verbs A and B can be fitted into this template; only use combinations that have already become fixed (such as 东张西望 dōng zhāng xī wàng 'look around in all directions', 东奔西跑 dōng bēn xī pǎo)—arbitrarily pairing verbs will be wrong.
