Chen was born into one of the lesser clans, the Hwi-clan, on Bothawui. His Uncle Far'hwi - a trader - took him under his wings and had him working on one of his ships. He supported Chen and soon made him pilot on one of his smaller freighters.
When Far'hwis business took a steep decline due to imperial restrictions and crime cartels demanding an ever lager cut of the profits in the outer rim, Chen soon found himself unemployed and having to make his own ways through the outer rim. He started going deeper into the smuggling business because that was all he was good at.
Chen and Far'hwi parted ways, but not on good terms. Far'whi wanted to keep Chen under his wings while Chen strove for independence. Far'whi thinks Chen to be selfish for this.
For Chen, independence is the greatest reward. As money and influence seems to be the best currency for this on the outer rim, he goes after these. High risk, high pay jobs have always been his favorite and so far he has been capable (or lucky) enough to live through them.
5 - Game Masters' discretion
10 - Favour. Chen owes some Black Sun Underboss a Favour for letting him proceed with a large shipment of "Slick" out of Vaynai while passing through Black Sun territory without having payed the proper passage "service fees"
5 - Addiction. Chen is mildly addicted to "Slick" or "Lessai" to cope with the long stretches of sleepless hours while on smuggling runs.
Chen is a quick witted Bothan and rather full of himself (he tends to refer of himself in the third person). This seems to get him into trouble more often than not, which he keeps discribing as "people just not being able to understand the greatness of Chen Oso'hwi!"
