…… (yìbiān…yìbiān…) says that one person is doing two things in the same stretch of time: ， “He watches TV while he eats.” Each stands directly in front of its own verb, after the subject — the subject is mentioned once, at the very start.
The single most important restriction is that both actions belong to the same person. For two different people acting at once, Chinese uses or instead: ，. Writing ， is not a stylistic slip; it is ungrammatical.
Both verbs also have to be activities that last. and are fine; instantaneous verbs such as , , cannot be spread across time and do not fit the frame.
In casual speech the pattern is often shortened to ……: . And for a posture held while doing something else, Chinese prefers rather than : “He spoke standing up”, not .
The pattern says nothing about tense. Add or a time word if you need it: .

对比
Most errors with this pattern are not errors about this pattern — they are a neighbouring pattern arriving at the wrong moment. Read these side by side.
在 and 一边…一边… both describe something in progress, but they answer different questions. 在 says that a single action is under way right now: 他在吃饭 “He’s eating.” 一边…一边… says that two actions overlap: 他一边吃饭一边看电视. You cannot stack them — 他在一边吃饭一边看电视 is redundant, because the frame already places both actions in the same running moment. If only one activity is involved, 在 is the right tool; the moment a second activity shares the time slot, switch to 一边…一边….
