Notice:
*The definition of China includes all administrative regions listed in 6.2.
*Although Hong Kong, Macau, Taiwan, Huangyan Island, and Dongsha Islands have separate DXCC prefixes, they all belong to China, and there is no separate award-winning quota，but they count for DXCC multipliers.
5.1 Single opeartor categories
5.1.1 Only one signal is allowed to on air at any time during the contest.
5.1.2 All operations, logging and spotting functions can only be completed by a single participant, and no other operator is allowed to assist in listening or sending.
5.1.3 For the single operator field all band category ( SOAB-FD-L , SOAB-FD-Q , note: the field category is only suitable for Chinese participants) , all antennas must be erected temporarily, and line power cannot be used as a power supply. When submitting the log, photos of the station location, antenna, equipment, etc. are attached to help the competition committee determine whether the competition is in a typical field environment.
5.2 Multi operators categories
5.2.1 Multi operators and multi transmitters (MM) : There is no limit to the numbers of transceiver, and the power is not distinguished in the all band, but each band can only have one transmitting signal at the same time.
5.2.2 Multi operators dual transmitters (M2-L) : limited to low power (no more than 100W) all bands, allowing simultaneous operation of two bands, but each band can only have one transmit signal at the same time.
6. Information for exchanges:
Suggested calling method: CQ WAPC
6.1 Non-Chinese participants： signal report + QSO serial number, starting from 001, such as 59 (9) 001.
6.2 Chinese participants: signal report + province/municipality/autonomous region/special administrative region abbreviation, for example 59 (9) BJ.

7. QSO points
7.1 For Chinese participants:
- QSO between stations in 34 provinces/municipalities/autonomous regions/special administrative regions : 1 point
- QSO with other Asian DXCC countries other than 34 provinces/municipalities/autonomous regions/special administrative regions : 1 point
- QSO with stations from other continents : 3 points
- QSO with marine mobiles (/MM) and air mobiles (/AM) not counts multiplier, but worth 2 points for any participants
- The QSO points on the 10m and 40m bands is multiplied by 2, and the QSO points on the 80m band is multiplied by 4
7.2 Non-Chinese participants:
- QSOs with stations within the same continental: 1 point
- QSO with stations from different continents : 3 points
- QSO with marine mobiles (/MM) and air mobiles (/AM) not counts multiplier, but worth 2 points for any participants
- The QSO points on the 10m and 40m bands is multiplied by 2, the QSO points on the 80m band is multiplied by 4
- The QSO with Chinese stations is multiplied by 2 after the above score
8. Multipliers
8.1 A multiplier is counted in each band with each different province/municipality/autonomous region/special administrative region of China.
8.2 Counts a multiplier for each different DXCC entities in each band.
9 Scoring
Final score = total QSO points × sum of multipliers (i.e. Chinese provincial multipliers + DXCC multipliers).
10 Dupes
10.1 Duplicate contacts refer to communications between the same station in the same band. If the first contact between two stations is valid, the following duplicated contacts counts 0 points. If the first contact is invalid, the second (or following duplicates) call will be accepted.
10.2 Duplicate contacts will not be penalized. Nor does it need to be identified in the contest log submission. Additionally, entrants are advised to keep a record of duplicate communications in the contest log. Do not delete duplicate contacts!
