法属印度支那贸易银圆，俗称坐洋，为清末在华流通的外国银圆之一。银元正面希腊自由女神坐像，这也是“坐洋”得名的原因。坐洋的前身为法国政府在交趾支那（南部越南政权）于1879年 。开始铸造10仙（Cent，也译作“分”，下同）、20仙、50仙、1皮（piastre，音译皮阿斯特，法制单位元）的交趾支那（cochin china）银币。时至1885年，法属安南政府为抵制墨西哥银币及美国贸易银币，于1885年开始铸造一元银币。

French silver trade in India, commonly known as "Yang Yang", is one of the foreign silver coins circulated in China at the end of the Qing Dynasty.The silver dollar is the statue of the Greek goddess of liberty. This is also the reason why "Yang Yang" has been named. The former government of France was the * * * government of the French government in 1879.Sit in the ocean Began casting 10 Immortals (Cent, also translated as "sub", the same below), 20 immortals, 50 immortals, 1 * * * (piastre, transliteration P Astor, legal unit yuan) Cochin China. In 1885, the French Annan government began to mint one-dollar silver coins in 1885 to boycott the Mexican silver coins and the American trade silver coins.

由于坐人开始铸造无论从成色及重量（27.215克，90%成色，1885年-1895年制规格，被称为加重坐洋）上都优于鹰洋，很快就占领了统治地位。也正因为其纯重高于墨西哥鹰洋（27克），多有藏匿及熔化者，故不能流通。因此，于1895年将重量减低，将一元坐洋的重量由原来的27.215克减至27克（1895-1928年制规格，被称为普重坐洋）。也正是因为其成色高重量足，晚晴以至民国，在中国南部的云南，广西、广东、福建沿海以及国内大部分商贾聚集地通用。一元坐洋于1928年停铸，随后于1931年以谷物女神头像重新开铸了1元，其的设计图案、重量（1931制减重为20克，成色不变）已和原先的坐洋迥异，人们习惯上仍然称其为坐洋，但须折价使用。

As the seats began to cast, they were superior to Eagle Ocean in both fineness and weight (27.215g, 90% fineness, 1885-1895 specifications, known as aggravated seats), and soon gained dominance. It is precisely because its pure weight is higher than the Mexican Eagle Ocean (27 grams), there are many hide and melt, so it can not circulate. Therefore, in 1895, the weight was reduced from 27.215 grams to 27 grams (1895-1928 specifications, known as the universal recoil). It is precisely because of its high quality, high weight, evening sunshine and even the Republic of China, in southern China's Yunnan, Guangxi, Guangdong, Fujian coastal areas and most of the domestic merchants gathered in general. It was stopped casting in 1928, and then recasted in 1931 with the head of the cereal goddess. Its design and weight (weight reduced by 1931 to 20 grams, and the color remained unchanged) were different from the original seating. People still used to call it seating, but it had to be used at a discount.

“坐洋”的主币“壹圆”的铸造时间从1885年开始，在巴黎铸造，至1928年共计43年。该主币1885年至1895年年号的铸币均为27.125克重，称之为“加重版”；1895年至1928年的24个年号的铸币重量均为27克重，称为“普通版”。值得注意的是，1895年是加重版和普通版同铸的年号，另有有传闻1905年有“加重版”，但至今未发现实物，其真实程度尚无法判定。

On the back of the oceanThe casting time of the main coin "one circle" began in 1885, and was cast in Paris for a total of 43 years to 1928. The coins of the year 1885 to 1895 weighed 27.125 grams and were called "heavier editions". The coins of the 24 years from 1895 to 1928 weighed 27 grams and were called "ordinary editions". It is noteworthy that 1895 was the year of the aggravated edition and the ordinary edition, and there are rumors that there was an "aggravated edition" in 1905, but so far no physical object has been found, the authenticity of which can not be determined.

“坐洋”由主币和辅币共4枚组成一套。称呼辅币时，通常以“坐洋半圆”“坐洋50分”“中坐洋”，或“坐洋二毫/一毫”“坐洋20分/10分”“10/20仙小坐洋”一类称呼。

"Yang Yang" consists of 4 pieces of main currency and fractional currency. When addressing tokens, they are usually referred to as "sitting in the ocean half circle", "sitting in the ocean 50 points", "sitting in the ocean 50 points", "sitting in the ocean 2 millimeters/1 millimeter", "sitting in the ocean 20 points/10 points", "10/20 immortals sitting in the ocean" and so on.

“坐洋”的形象虽然与其后英国铸造的“站洋”中持戟武士傲然挺立船头的形象大相径庭，但却丝毫无法掩盖殖民主义者大规模进行经济侵略的野心

Although the image of "sitting on the ocean" is quite different from the image of the halberd warrior standing proudly on the bow in the "standing on the ocean" created by Britain, there is nothing to hide the colonialists'ambition of large-scale economic aggression.
