A compound directional complement consists of a verb + two directional words (e.g., 走进来 = walk + in + come). Rule A (Location Object): If the object is a PLACE/LOCATION, it MUST go BEFORE 来/去. This is an absolute rule with no exceptions. Rule B (Thing Object): If the object is a THING, it can go either before OR after 来/去. However, when the action is completed, the object tends to go AFTER 来/去.

"一边…一边…" expresses that two actions are happening AT THE SAME TIME. Both verbs describe actions performed simultaneously by the same subject.
In spoken Chinese, the 一 (yī) before 边 is often dropped, giving the shorter form "边…边…". Both forms are correct — the full form is slightly more formal. Note: The two actions should be compatible (can actually happen at the same time). You cannot say 一边睡觉一边跑步 (sleeping while running) — that's physically impossible!
