Chen Youliang
In 1354 Chen Youliang, the founder of the rebel Chen Han regime in the late Yuan Dynasty tried to mobilise support from Đại Việt. However the Emperor Trần Dụ Tông refused to help him because the Trần Dynasty needed to concentrate their force in the southern border against Champa. In the account about this event, Ngô Sĩ Liên noted that the Chinese leader Chen Youliang (陈友谅；Vietnamese: Trần Hữu Lượng), founder of Chen Han in China, was the son of Trần Ích Tắc.
