次 vs 趟 (cì vs tàng): occurrence vs round-trip
Both 次 (cì) and 趟 (tàng) are classifiers for action frequency, but 次 is the general-purpose counter for occurrences of any event, while 趟 specifically counts round-trip journeys or trips to a place. Use 次 for ordinary repeated actions (e.g., reading a book twice), and 趟 for trips that involve going and coming back (e.g., three trips to the post office).
次 (cì) and 趟 (tàng) are both classifiers used to indicate how many times an action occurs, but they differ in the type of action they describe. 次 is a general classifier for occurrences – you can use it for almost any repeated action, from reading a book to visiting a city. 趟 is more specific; it describes a trip that involves going to a destination and coming back, or a complete journey (often involving travel). While 次 can sometimes substitute for 趟 in informal speech, using 趟 for a non-travel action (like reading a book) is incorrect. Learning to distinguish them helps you speak with greater precision about travel and routines.
When to use each
Use 次 as the default counter for the number of times an action happens, regardless of whether it involves travel. It works with verbs like 看 (read/watch), 去 (go), 吃 (eat), 做 (do), etc. For example, 'I have seen that movie three times' uses 次. 次 is also used for frequencies in everyday life, such as 一次 (once), 两次 (twice), or 多次 (many times). It is the safest choice when you are not sure which classifier to use.
Use 趟 specifically for a round trip – going to a place and returning – or for a complete journey with a destination and return. Common verbs include 去 (go to), 跑 (run an errand), 飞 (fly to), 走 (walk to). For example, 'I went to Shanghai three times this year' could use 趟 if each trip involved going and coming back. 趟 often implies the action is a trip or errand, not just a single one-way visit.
趟 can also be used for the number of trips on public transportation routes (e.g., 这趟车 means 'this train/bus route'). In such cases, it refers to a scheduled journey, not necessarily a round trip by the same person, but still a designated route with a start and end.
At a glance
| 次 | 趟 | |
|---|---|---|
| Core meaning | General occurrence or instance | Round-trip journey or errand |
| Typical verbs | 看, 吃, 做, 去, 来, 写, etc. | 去, 跑, 飞, 走, 坐 (vehicle), 开 (drive) |
| Implies round trip? | No – just the event itself | Yes – going and coming back |
| Can modify travel? | Yes, but neutral about round-trip | Yes, and emphasizes the journey aspect |
| Usage scope | Very broad; almost any action | Narrow; only for trips/journeys |
Examples
- 次我去过两次北京。Wǒ qù guo liǎng cì Běijīng.I have been to Beijing twice.次 is fine here; it simply counts the occurrences of going to Beijing, without specifying whether each trip was a round trip.
- 趟今天他跑了三趟银行。Jīntiān tā pǎo le sān tàng yínháng.He made three trips to the bank today.趟 is appropriate because each trip to the bank involved going and coming back (an errand).
- 次这本书我看了三次。Zhè běn shū wǒ kàn le sān cì.I have read this book three times.Use 次 for actions like reading that do not involve travel.
- 趟我坐这趟车去上海。Wǒ zuò zhè tàng chē qù Shànghǎi.I will take this train to Shanghai.趟 here refers to a specific scheduled train route (a journey).
- 次他去了一次美国。Tā qù le yī cì Měiguó.He went to the US once.次 is used; the focus is on the occurrence, not on the round-trip nature. If the round-trip aspect is important, 趟 could also be used, but 次 is more neutral.
Common mistakes
- Using 趟 for non-travel actions: '我今天跑了三次步 (jogged three times)' should use 次, not 趟, because jogging is not a round-trip errand.
- Using 次 when emphasizing round-trip: In contexts where each occurrence is clearly a journey back and forth, 趟 sounds more natural. For example, '我今天去超市买了三次东西' – if each trip was separate, 趟 is better: 跑了三趟超市.
- Confusing 趟 with 遍 (biàn, 'throughout'): 趟 counts trips, while 遍 counts the number of times an action is completed from start to finish (like reading a book cover to cover).
- Overgeneralizing 趟 to one-way trips: 趟 implies return; for a one-way trip, 次 is more accurate (e.g., 我去一次上海就不回来了 – 'I go to Shanghai once and won't come back').
FAQ
- When should I use 次 vs 趟?
- Use 次 for general occurrences of any action, whether travel or not. Use 趟 only for trips that involve going to a place and coming back (round trips) or for scheduled journeys (e.g., train routes). If in doubt, 次 is usually safe.
- Can I use 趟 for a one-way trip?
- No, 趟 specifically implies a round trip (or at least a journey with a return). For a one-way trip, use 次. For example, '我去了一次北京，然后留下来了' (I went to Beijing once and then stayed).
- Is 趟 only for physical travel?
- It is primarily for physical travel (walking, driving, flying), but it can also be used metaphorically for errands or even a complete 'round' of something (e.g., 跑一趟腿 – run an errand). It is not used for abstract actions like reading or watching.
- Are there fixed expressions that require 趟?
- Yes, common phrases include 跑一趟 (run an errand), 来一趟 (make a trip here), 去一趟 (go on a trip). You also see it in transportation announcements: 这趟航班 (this flight). In such cases, 趟 is fixed and cannot be replaced by 次.
