China: why does one embassy have three dates?

Compare a mission to the Qing court across three calendars, then explore projects about places, records and China–Romania ties.

Choose a date and compare how it appears in the embassy report and the Qing calendar.

Three dates for one embassy

Which date appears in each record?

At Beijing, Russia used the Julian calendar while the Qing court used a lunar calendar. The conversions below are documented in the embassy project.

EVENT

The letter reaches the court

The embassy report describes the tsar’s letter arriving on a yellow-covered table. For this day, the project aligns the Julian date, its Gregorian conversion and the date in the Qing chronicle.

Embassy report · Julian
5 June 1676
Conversion · Gregorian
15 June 1676
Qing chronicle · lunar
Kangxi year 15 · month 5 · day 5 (bingxu)

This entry follows the embassy report and the Kangxi reign chronicle; the records do not preserve the same level of detail.

The embassy report runs to more than 100 pages; Kangxi’s reign chronicle preserves four entries about the entire mission. This comparison shows which records survive, not everything said at court.

Two archives, very different lengths

The embassy report spans more than 100 pages in the edition used by the project. Kangxi’s official reign chronicle preserves four entries about the entire mission. Read each account within its limits.

02

China does not fit on one map

Qinghai Lake, the Yangtze, Beijing and river names pose questions at different scales. The collection sets them beside projects about journeys, language and cultural exchange.

Beijing's walls, along the metro route

Beijing's Line 2 follows the former inner-city enclosure corridor, and several stations carry the old gates' names. Ride all 18 stops — 8 inner-gate names, 3 later openings, 7 without a counterpart — then compare Liang Sicheng's unbuilt wall-top park with the 1952–1970 demolitions and count what remains: 2 gate sites, 3 towers, wall fragments.

The other side of the Moon: why it looks so different, and who has landed there

Turn a globe of the Moon and watch the dark seas almost disappear: they cover 30% of the near side and 2% of the far side. With a map of crust thickness, the South Pole–Aitken basin, the places where Chang’e 4 and Chang’e 6 landed, and what the first samples brought back from there say.

03

Cultural exchange leaves evidence

Films, books, games, food and words leave different records. Some projects verify an edition or a screening date; others compare forms without treating China as a uniform culture.

Romanian films in China, 1950–1992: 68 films and the titles China gave them

Between 1950 and 1992 at least 68 Romanian feature films were dubbed or shown in China. Each is listed with its Chinese and Romanian titles, the year it opened in Romania, the year and studio of its Chinese dubbing, and its sources. One 1955 spy film had six million admissions in China by 1958, according to the People's Daily. In Romanian, English and Chinese.

Chess and xiangqi (Chinese chess): one army on two boards, compared piece by piece

Chess and xiangqi set out the same army: chariot, horse, elephant, counsellor, king. Pick a piece and see its move on three boards: shatranj, the medieval game, chess today and xiangqi. The medieval bishop reached 8 of 64 squares; the xiangqi elephant reaches 7 of 90 points. With the names of the pieces in 31 languages and a ten-move quiz. In Romanian, English and Chinese.

The Romanian word for “plate” comes from a title of China’s emperor

Where Romanian farfurie, “plate”, comes from: Ottoman farfuri, “porcelain”, and before it Persian faghfūr, the title given to the emperor of China. Turn a Ming dish to see the word’s seven forms, from 天子 to farfurie, each with its source. With the Chinese province that dictionaries invented, the map of the routes and the Topkapı collection.

The seasons: why the year turns, how many seasons the world counts and what 351 languages call them

The sky gives the year four fixed points: two solstices and two equinoxes. People decided the rest: two seasons in Iceland’s old calendar, three in ancient Egypt, six in India, 24 solar terms in China and 72 in Japan’s old almanac. The page draws 21 calendars as rings of one year, shows why there are seasons at all, where the four words come from in 64 languages, and what the oldest text found says for eighteen stories about the turning year.

Current ties need a date

Visa rules, trade and public statements change. Their pages retain a date and source, and Taiwan is identified separately where it appears.

The complete collection

Projects about China’s places, records and exchanges, plus a few documented China cases in other fields; Taiwan remains separately identified.

About the collection

The collection includes projects centred on China, a documented China connection, or an explicit exchange with a Chinese institution, language or community. An incidental mention is not enough. Taiwan appears only in the project about its tax-receipt lottery and is identified separately. Current claims keep the date and sources of their own project. It also includes a small number of projects with a substantial China case: banking reform, cyber operations, students, lunar missions, solar terms and Everest’s Tibetan side. Actor labels in the cyber report do not prove that a government ordered an operation.
