Director Chen Kwan-hau - 16 years between pictures?

Just curious about this guy's credits:

A cinematographer since at least 1970, he directs (and photographs) a movie called MY MOTHER'S TEA HOUSE in 1990, then disappears for 16 years only to return with TWIN DAGGERS, a cheapo pan-cultural martial arts flick that doesn't fit in with his prior CV in any logical way and seems designed solely for a DTV release in the U.S.? I suppose it's possible, but I'm thinking a split might be needed here . . .
