Introduction:
We learned about Result Complements. Now, let's talk about Directional Complements. These indicate the direction of an action. The simplest and most common ones are 来 (lái - to come) and 去 (qù - to go). They are added after another verb to show movement towards or away from the speaker.

The Basic Rule:

• Verb + 来: Movement towards the speaker.

• Example: 进来 (jìn lái) - to come in

• Verb + 去: Movement away from the speaker.

• Example: 进去 (jìn qù) - to go in

Think of a room:

• If you are inside the room, you say: "请进来 (Qǐng jìn lái)" - "Please come in." (The person is moving towards you).

• If you are outside the room, you say: "我进去了 (Wǒ jìn qù le)" - "I'm going in." (You are moving away from your current location).

More Common Examples:

• 上 (shàng - to ascend) + 来/去:

• 上来 (shàng lái) - to come up

• 上去 (shàng qù) - to go up

• 下 (xià - to descend) + 来/去:

• 下来 (xià lái) - to come down

• 下去 (xià qù) - to go down

• 回 (huí - to return) + 来/去:

• 回来 (huí lái) - to come back

• 回去 (huí qù) - to go back

Example in a Dialogue:

• A (downstairs): 你在哪儿？ (Nǐ zài nǎr?) - Where are you?

• B (upstairs): 我在楼上，你快上来吧！ (Wǒ zài lóu shàng, nǐ kuài shàng lái ba!) - I'm upstairs, come up quickly!
